1788 Quarter Value Checker: Errors List, “D”, “P” & “S” Mint Mark Worth

The “1788” stamped on these quarters doesn’t mean they were struck in colonial times — it marks the year each state ratified the Constitution and joined the Union. These coins are part of the 50 States Quarters Program, actually minted between 1999 and 2001, representing the eight founding states: Georgia, Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, and New York.

The coins as part of the 50 States Quarters Program is the most successful numismatic program in U.S. history, with roughly half the American population collecting them.

That kind of cultural reach, combined with billions of coins in circulation, creates a wide value spectrum: most circulated examples are worth exactly $0.25, while uncirculated coins from the Philadelphia and Denver mints can fetch anywhere from a few dollars to over $100, and San Francisco silver proof versions command a meaningful premium above that.

Where a specific coin lands in that range depends on state, mint mark, grade, and whether any errors are present — which is exactly what the 1788 Quarter Value guide below breaks down.

 

1788 Quarter Value By Variety

With 32 varieties across eight states and three mint facilities, knowing exactly which 1788 quarter you have is the first step to understanding what it’s worth. If you know the grade of your coin, you can find the exact price below in the Value Guides section.

Grade matters, but it doesn’t tell the whole story. The 1999-S Georgia Silver PR 70’s $6,038 record sits in a league of its own — nearly half again what the second-place coin fetched. Strip that away, and the chart becomes a referendum on timing: coins from 1999 consistently punch above their weight regardless of grade, with Connecticut and Georgia business strikes from Philadelphia clearing $4,000 even without the silver premium.

South Carolina shows up twice — Philadelphia and Denver — separated by over $500 despite similar grades, hinting that mint mark still plays a quiet role in the hierarchy. Massachusetts and New Hampshire sit close together in the $3,500–$3,760 band, neither distinguishing itself dramatically from the other.

At the bottom, New York’s 2001-P MS 69 and the two Connecticut entries round out the top ten despite strong grades. New York, as the last 1788-series coin released, never quite caught the early-program enthusiasm that inflated prices for Georgia and Connecticut. The takeaway: in this series, being first mattered more than being perfect.

 

History of the 1788 Quarter

The 1788 Quarter isn’t a relic of colonial America — it’s a product of late 1990s Washington politics. The idea originated in December 1993, when the Citizens Commemorative Coin Advisory Committee first proposed honoring each of the 50 states with a unique quarter design.

The Treasury Department opposed it, fearing it would lead to a “Disneyfication” of U.S. coinage. It took years of lobbying, an independent feasibility study, and a congressional mandate before the program finally cleared. President Bill Clinton signed the 50 State Commemorative Coin Program Act into law on December 1, 1997.

Launched in 1999, the program released five new quarters each year in the order that states ratified the Constitution or were admitted into the Union.

That sequencing is exactly why eight coins carry the date 1788 — Georgia was the first state to ratify that year, in January, followed by Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, and finally New York in July.

Each design was selected through statewide contests open to local sculptors and artists, with U.S. Mint staff engraving the chosen concepts onto the coins.

What began as a contested bureaucratic proposal ended up becoming, by any measure, a cultural phenomenon.

Is Your 1788 Quarter Rare?

Most 1788 quarters spent decades passing through millions of hands unnoticed — but a few slipped through the mint with errors or survived in flawless condition, and those are the ones worth a second look. To find out which category yours falls into, the fastest starting point is the Coin Value Checker App.

 

Key Features of the 1788 Quarter

Washington’s cheekbone, a peach, a charter oak, nine stars — the 1788 quarter packs more American history into 24.3 millimeters than most people ever stop to notice.

The Obverse of the 1788 Quarter

Every 1788 quarter shares an identical obverse: the classic portrait of George Washington facing left, with “United States of America” arching above his head, “Liberty” near his Adam’s apple, and “In God We Trust” behind his neck. The mint mark — P, D, or S — sits just below the motto, and “Quarter Dollar” runs along the bottom. The designer initials JF and WC, for John Flanagan and William Cousins, appear on the neckline cutoff.

The Reverse of the 1788 Quarter

The reverse design was left to each state, resulting in eight distinct coins that reflect the values and character of each.

• Georgia— A peach at the center of the state outline, flanked by two live oak sprigs, with three banners displaying the state motto “Wisdom, Justice, Moderation.”
• Connecticut— The legendary Charter Oak, with a small brick hedge to its right and the inscription “The Charter Oak” to the left of the trunk.
• Massachusetts— The Minuteman statue with an outlined state map in the background.
• Maryland— The Maryland State House dome flanked by White Oak leaf clusters, with the nickname “The Old Line State.”
• South Carolina— The state outline with a star marking the capital Columbia, the Palmetto tree, the Carolina Wren, and the Yellow Jessamine.
• New Hampshire— The Old Man of the Mountain rock formation with the state motto “Live Free or Die.”
• Virginia— Three historic ships — the Susan Constant, Godspeed, and Discovery — commemorating the Jamestown settlement.
• New York— The Statue of Liberty with the state outline and eleven stars, under the theme “Gateway to Freedom.”

Other Features of the 1788 Quarter

The 1788 quarter has reeded edges and a weight of approximately 6 grams, with a diameter of 24.3 millimeters. Clad versions are composed of 91.67% copper and 8.33% nickel, while silver proof versions contain 90% silver and 10% copper.

1788 Quarter Mintage & Survival Data

Business strikes from Philadelphia and Denver dominate the mintage figures — Virginia’s Philadelphia issue leads the entire series at 943,000,000 pieces, while even the smallest regular-issue coin, the 1999-P Georgia, came in at 451,188,000. Survival rates across all circulation strikes sit uniformly at 75%, meaning roughly 338 to 707 million examples of each variety remain in existence today.

Proof issues tell a completely different story. Clad DCAM coins from San Francisco were struck in the 3 to 4.8 million range, with survival rates jumping to 95% — a direct result of collector handling from day one. Silver DCAMs are scarcer still, with most states seeing fewer than 965,421 pieces struck and survival rates holding at 94.9999%.

The lone outlier worth noting is the 2000-S New Hampshire Clad DCAM, which dips to an 82.57% survival rate against a mintage identical to its peers — a subtle anomaly that sets it apart within an otherwise uniform proof segment.

The Virginia (PL) entry stands alone with both survival and survival rate listed as unknown, suggesting these polished-die specimens were never formally tracked at scale.

The Easy Way to Know Your 1788 Quarter Value

Pinning down an accurate 1788 quarter value comes down to three things: variety, condition, and real auction data. Check the state on the reverse, locate the mint mark below “In God We Trust,” and assess wear on Washington’s cheekbone and the high points of the reverse design — those details alone will tell you whether you’re holding pocket change or something worth grading.

For a faster read, the Coin Value Checker App  cross-references your coin against certified sales and live auction records, returning an accurate market value in seconds.

 

1788 Quarter Value Guides

The 1788 quarter isn’t a single coin — it’s a family of eight distinct state issues, each struck across multiple mint facilities. Knowing which combination of state and mint mark you have is the starting point for any accurate valuation.

• Georgia (1999) — P, D, S (Clad & Silver Proof)
• Connecticut (1999) — P, D, S (Clad & Silver Proof)
• Massachusetts (2000) — P, D, S (Clad & Silver Proof)
• Maryland (2000) — P, D, S (Clad & Silver Proof)
• South Carolina (2000) — P, D, S (Clad & Silver Proof)
• New Hampshire (2000) — P, D, S (Clad & Silver Proof)
• Virginia (2000) — P, D, S (Clad & Silver Proof)
• New York (2001) — P, D, S (Clad & Silver Proof)

Philadelphia (P) and Denver (D) handled all circulation strikes, producing coins that entered everyday commerce by the hundreds of millions. San Francisco (S) struck exclusively for collectors — first in clad proof, then in silver — at a fraction of the volume. The result is a series where the same state design can exist in forms that differ not just in finish, but in scarcity and collector demand by an order of magnitude. Virginia is the most heavily struck of the eight; Georgia, as the first release, carries the strongest early-program premium. Every variety in between has its own story, and its own value.

 

1788 Georgia Quarter Value

The Georgia quarter holds a distinction no other coin in the series can claim: it was the first 1788-dated quarter ever released, hitting circulation on July 19, 1999, and by extension, the coin that kicked off the entire 50 States Quarters program in earnest.

Georgia was the fourth state to join the Union, ratifying the U.S. Constitution on January 2, 1788 — a fact that places it near the front of the constitutional order and gives the coin an early-program prestige that later issues simply can’t replicate.

Coins from this year often show uneven pressure or soft detail, so pieces with sharp lettering and a clear peach design are harder to find and command higher premiums.

That strike inconsistency, combined with Georgia’s status as the program’s first major release, is precisely why high-grade certified examples attract serious collector attention — and why the Georgia quarter remains one of the most closely watched issues across the entire 1788 series.

The chart below traces how Georgia’s status as the program’s first-ever release has shaped its auction record over time.

First out of the mint and first into collections — market activity for the Georgia quarter has held steadier than most in the series.

 

1788 Connecticut Quarter Value

Connecticut became the fifth state to ratify the Constitution on January 9, 1788, and its quarter — released on October 12, 1999 — holds the distinction of being the final issue of the 20th century in the 50 States Quarters series.

The reverse centers on the Charter Oak, a tree steeped in colonial resistance: on October 31, 1687, Royal Governor Sir Edmund Andros demanded Connecticut surrender its royal charter, and the colony refused — with the charter reportedly hidden in the Charter Oak to keep it from British hands.

What makes the design particularly poignant is that the tree dated back perhaps to the 12th century and fell during a storm in 1856 — meaning the coin commemorates something that no longer exists, placing it alongside the New Hampshire quarter as one of only two 1788-series issues depicting a vanished landmark.

Among the eight states, the Connecticut quarter consistently commands the strongest auction results for business strikes, with a 1999-P MS68 example reaching $4,362 and a 1999-D MS68 fetching $2,300.

Auction results for the Connecticut quarter reflect collector appetite for one of the most historically charged designs in the entire series.

The final coin of the 20th century continues to draw consistent collector interest, as the data below shows.

 

1788 Massachusetts Quarter Value

The Massachusetts quarter carries a design origin unlike any other in the series. The state limited design submissions exclusively to schoolchildren, and two students — a sixth-grader and a seventh-grader — were selected as co-winners of the statewide competition, making the Minuteman design uniquely the work of young Americans, not professional artists.

The reverse depicts the Minuteman statue — a figure based on the self-formed civilian militias who assembled to fight the British at a moment’s notice — set against an outline of the state.

Released on January 3, 2000, it carries another distinction: it was the first quarter of the new millennium. In terms of value, the Massachusetts quarter occupies a commanding position at the top of the 2000 series.

A 2000-D Massachusetts quarter graded PCGS MS-69 sold for $9,000 — the highest recorded price for any business-strike 2000 State Quarter — while a Philadelphia MS-69 example reached $7,000.

The market data below captures how a coin designed by schoolchildren became the highest-priced business strike of the 2000 issues.

A design born in a classroom, now tracked in auction houses — market activity for the Massachusetts quarter reflects its outsized reputation among 2000 issues.

 

1788 Maryland Quarter Value

Few coins in the series carry as much layered history as the Maryland quarter.

The reverse depicts the dome of Maryland’s State House — the oldest state capitol building still in continuous legislative use in the United States — where the Continental Congress met from 1783 to 1784 to ratify the Treaty of Paris, officially ending the Revolutionary War, and where George Washington resigned his commission as Commander-in-Chief on December 23, 1783.

The nickname “The Old Line State,” inscribed on the reverse, adds another dimension: it honors Maryland’s “troops of the line,” soldiers who earned praise from Washington himself for their steadfast defense during the Revolution.

Notably, the dome is also the largest wooden dome in the United States built entirely without nails — a structural feat that makes it an even more fitting centerpiece for a commemorative coin.

Among collector grades, a Philadelphia Maryland quarter struck on a nickel planchet — a wrong-metal error — brought $1,495 in MS65 at Heritage Auctions in January 2005.

The chart below shows how grade and strike quality drive premiums on a coin whose reverse tells more American history than most textbooks cover in a chapter.

With more history packed into its reverse than most coins twice its age, the Maryland quarter maintains reliable demand across grade levels.

 

1788 South Carolina Quarter Value

The South Carolina quarter stands out for two reasons that have nothing to do with condition or grade. First, its reverse packs three official state symbols — the Palmetto tree, the Carolina Wren, and the Yellow Jessamine — into a single composition that reads as one of the most visually balanced designs in the entire series.

The palmetto tree carries particular historical weight: palmetto log fortifications withstood British naval bombardment during the 1776 defense of Charleston Harbor, making the tree a symbol of resilience that predates the Constitution itself.

Second, and uniquely among all 50 state quarters, the designer of this coin remains unknown — no one ever stepped forward to claim responsibility for the anonymous entry submitted to the South Carolina Department of Parks, Recreation, and Tourism design contest.

At auction, a 2000-D South Carolina in MS63 realized $2,990 at Heritage Auctions in September 2003, while a Philadelphia MS-69 example later reached $3,525.

Below is the auction record for a quarter whose designer remains anonymous to this day.

Three state symbols, one anonymous designer, and a market that rewards condition above everything else.

 

1788 New Hampshire Quarter Value

The New Hampshire quarter holds a distinction shared with only one other coin in the series: it depicts a landmark that no longer exists. The reverse centers on the Old Man of the Mountain, a granite rock formation towering over 40 feet tall in Franconia Notch, whose stoic human-like profile had captured generations of imaginations — until it collapsed due to natural erosion in May 2003, just three years after the coin entered circulation.

The collapse transformed the quarter overnight from a standard commemorative into an unofficial memorial, and many collectors and New Hampshire residents began actively seeking out these quarters as a way to preserve the memory of a cherished state symbol.

The design also carries a numerical detail worth noting: nine stars surround the formation, signifying New Hampshire’s status as the ninth state to ratify the Constitution.

At auction, a Philadelphia MS64 example realized $2,128 at Scotsman Auctions in January 2004, reflecting early program enthusiasm, while a PR69 clad DCAM proof brought $881 at Heritage Auctions in February 2013.

The data below tracks market activity for a coin that became a memorial the moment its subject ceased to exist.

Market activity for a quarter that stopped being just a quarter in May 2003.

 

1788 Virginia Quarter Value

The Virginia quarter is defined by two superlatives: the highest mintage of any coin in the 1788 series, and one of the most forward-looking designs in the entire 50 States program.

The reverse uniquely commemorated the Jamestown 400th anniversary seven years in advance, linking 1607’s founding to 2007’s celebration through the inscription “Jamestown 1607–2007” — a design decision that embedded a future event into a coin struck in the present.

The three ships depicted — Susan Constant, Godspeed, and Discovery — carried the first English settlers from London on December 20, 1606, arriving on May 12, 1607 to establish the first permanent English settlement in America.

Virginia also introduced a rare variant within the series: Philadelphia production occasionally yielded Prooflike (PL) specimens — business strikes from freshly polished dies exhibiting mirror-like fields similar to proof coins. At the highest grade levels, a PCGS MS68 Denver example has sold for approximately $650, with only 17 coins certified at that tier.

The chart below reflects how the most-produced coin in the 1788 series performs at the grades where scarcity finally kicks in.

Over 1.5 billion struck — yet the market data below shows exactly where scarcity begins.

 

1788 New York Quarter Value

The New York quarter entered circulation on January 2, 2001 as the final coin in the 1788 series — and within months, circumstances beyond numismatics would permanently alter its place in American culture.

When the coin hit circulation in early January 2001, it was well received but not particularly remarkable. This changed entirely on September 11, 2001, when the New York quarter — bearing the Statue of Liberty and the inscription “Gateway to Freedom” — took on a larger symbolic significance that no mint directive could have anticipated.

The coin became a patriotic memento of hope and endurance, sold by the millions in mass-market advertisements as collectors sought it out following the attacks.

The design itself reflects a democratic process: 76% of the public voted for the Statue of Liberty design, and Governor Pataki personally requested that a line be drawn on the reverse to represent the Erie Canal.

Of the coins graded, 626 have reached MS68 at a guide price of $40 — common enough to be accessible. Above that, only a single example has been certified MS68+, valued at $85, making it effectively a unicorn in practical terms.

MS69 coins number just 13, with a price guide of $975. That steep climb from 626 examples to 13 across just one grade point is exactly the kind of scarcity that drives serious collector interest — and explains why a 2001-P MS69 realized $2,585 at Heritage Auctions in January 2017.

Auction activity for the New York quarter — a coin whose meaning changed irreversibly on September 11, 2001.

Demand for the New York quarter has never quite separated itself from the events of the year it was minted.

Rare 1788 Quarter Error List

While billions of these coins were struck between 1999 and 2001, a select few escaped the mint with extraordinary errors — transforming ordinary 25-cent pieces into prized collectibles worth anywhere from a few dollars to over $100,000.

1. Mule Error

Mule errors are among the rarest and most collectible of all errors found on 1788 quarters. They occur when obverse and reverse designs that do not belong together are combined on a single coin. A “mule” is specifically an error coin produced by striking the obverse die of one denomination on one side of a blank planchet and the reverse die of a second denomination on the other side.

Prior to the discovery of this coin, mules were not known to exist in United States coinage, though they were commonly found in foreign series. The mule features the obverse of a Washington Quarter from the 50 State Quarters program and the reverse of a Sacagawea Dollar featuring an eagle in flight. Because both sides include their respective denominations, the coin carries a combined face value of $1.25. The discovery coin was found in May 2000 by Frank Wallis from Arkansas, who located the first authentic mule known on a U.S. coin — a 2000-P Washington Quarter obverse struck with the reverse of a Sacagawea Dollar.

As of September 2019, 19 examples have been confirmed, 16 of which are owned by a single collector named Tommy Bolack. On January 21, 2024, GreatCollections sold one of these rare mule error coins for a record $194,062.50 — surpassing the previous record of $192,000 set at a 2018 Stack’s Bowers auction. The mule was also ranked #1 in David Camire, Nicholas Brown, and Fred Weinberg’s 2010 book *The 100 Greatest U.S. Error Coins*, where it served as the centerpiece on the cover.

2. Tilted Partial Collar Error

A partial collar error occurs when the planchet is only partially confined by the collar during striking, leaving the lower half of the edge reeded while the upper half is smooth or beveled. A tilted partial collar takes this further — the collar sits at an angle during the strike, so one side of the coin’s edge is fully reeded while the opposite side flares out completely smooth. In extreme cases, tilt can be so great that one pole of the coin sits fully inside the collar while the other is completely above it, giving the coin a distinctive wedge-like profile when viewed from the edge.

Among 1788 quarters, documented examples include a 2000-P Virginia quarter and a 2000-P Massachusetts quarter, both certified by ANACS. Collectors are drawn to partial collar errors due to their significant yet subtle deformities, and values can be impressive — a 2001-D quarter graded MS69 with a partial collar error sold for $1,180 at a 2016 Stack’s Bowers auction. More recently, a 2007-P tilted partial collar Montana quarter graded MS65 fetched $725 at Heritage Auctions in 2020. As with most strike errors, the more dramatic the tilt and the higher the grade, the greater the premium.

3. Off-Center Strike

An off-center coin is produced when the coin is struck once but off-center, with the punch positioned toward the edge rather than the center of the planchet. This results in a coin that is not perfectly circular, with blank planchet space visible on one side.

The key rule for collectors is that a coin with the date still fully visible is worth significantly more. A quarter 20% off-center showing the date is far more desirable than one where the date has been pushed off the edge entirely. Minor off-center examples might be worth $10 to $50, but well-struck errors that still show the full date and state name can reach $200 to $500 or more. Quarters with over 50% off-center strikes in uncirculated condition have been known to sell for over $1,000 at auction. When hunting for these errors, look for blank planchet space crowding one edge while the design is pushed to the opposite side — the more dramatic the shift with the date still intact, the greater the value.

4. Clipped Planchet Error

A clipped planchet error occurs when the punches in the blanking machine overlap the leading edge of the metal strip or the hole left by a previous strike, producing either a straight clip or a curved clip. The result is a coin with a visible notch or arc missing from its edge.

Genuine clipped planchets have specific diagnostic characteristics. Straight clips show a flat, linear edge where the planchet overlapped the metal strip, while curved clips display a smooth arc matching the circumference of an adjacent blank. Among 1788 quarters, an MS 62 Georgia example with a clipped planchet error sold for $325, while an MS 66 Virginia example fetched $960. Values generally range from $35 to $300, depending on clip size, type, and coin composition. Collectors are advised to weigh any suspected clip coins, as a genuine clipped planchet will be measurably lighter than the standard quarter weight — a reliable way to distinguish a true mint error from post-strike damage.

5. Doubled Die Error

A doubled die error originates during die production when the hub impresses the design onto a die multiple times with imperfect alignment between strikes, causing letters, numbers, or design elements to appear distinctly doubled on the finished coin. This is critically different from the far more common “machine doubling,” which has no collector value.

True doubled die errors feature rounded, thickened letters with distinct notched split serifs where letter size appears to increase. Machine doubling, by contrast, produces flat, shelf-like smeared images where letter size decreases. Only genuine doubled die errors carry collector value.

On 1788 quarters, collectors should look for doubled die errors on Washington’s ear or the “IN GOD WE TRUST” inscription, with values typically ranging from $10 to $25 for minor examples. More dramatic examples with clear doubling across major design elements, particularly those certified by PCGS or NGC, can fetch $150 or more — and the bolder the doubling, the more fiercely collectors will compete for the coin.

6. Experimental Planchet Error

This error resulted from the U.S. Mint deliberately testing manganese brass in preparation for the Sacagawea Dollar of the year 2000. Instead of the standard clad quarter blanks, these coins were made with a pure copper core under a composition of 4% nickel, 7% manganese, 12% zinc, and 77% copper.

Because this alloy was intended for the golden-hued Sacagawea Dollar, state quarters accidentally struck on these experimental planchets stand out immediately due to their distinctive coloration. A golden or greenish tint may indicate an experimental planchet worth thousands of dollars. Collectors should examine their coins under strong lighting and weigh them carefully, as experimental planchet coins differ measurably from standard clad quarters.

A Georgia Quarter on an experimental planchet graded MS 67 sold for $7,200, while a Connecticut MS 66 example brought $5,100. Among the rarest known examples is a 1999-P Pennsylvania quarter struck on an experimental planchet — only a few are known to exist, with values exceeding $6,000.

7. Missing Clad Layer Error

A missing clad layer error occurs when one of the outer nickel layers is absent from the copper core, resulting in a coin that is copper on one side and nickel on the other. U.S. quarters are built as a three-layer sandwich — a pure copper core bonded on both sides by an outer copper-nickel alloy — and this clad composition has been standard since 1965.

A genuine missing clad layer coin will have a bright, lustrous copper surface with fully sharp struck design details intact, as the design was impressed cleanly into the exposed copper. Always verify weight: a genuine missing-clad coin is slightly underweight by approximately 1 gram, while an acid-treated coin — a common fake — still weighs a standard 5.67g.

For 50 State Quarters, the reverse side is far more desirable when missing its clad layer — worth five to ten times more than the obverse — because collectors want to see the copper side on the state design itself. A rarer variant is the dual missing clad layer, where both sides are stripped of their nickel coating. Only five to ten examples are known for Washington Quarters, and they typically sell for $1,000 to $5,000 depending on condition.

Standard missing clad layer state quarters can fetch between $100 and $300 in the current market, with coins missing both layers or in excellent condition potentially worth $500 or more. Among the 1788 quarter series, the 2000 Maryland quarter missing its nickel clad layer is a particularly well-known example and can be worth as much as $1,000.

FAQ about the 1788 Quarter

1. Are 1788 quarters actually from colonial times?

Not at all. Despite the date, these coins were produced between 1999 and 2001 as part of the 50 State Quarters Program. The “1788” refers to the year each featured state officially ratified the U.S. Constitution and joined the Union — not when the coin was minted.

2. Which eight states are represented on the 1788 quarters?

Eight states ratified the Constitution in 1788 and each received their own commemorative design: Georgia, Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, and New York. They were released in the order they joined the Union, starting with Georgia and ending with New York.

3. I found a 1788 quarter in my change. Is it worth keeping?

Most likely it’s worth only face value — 25 cents. Hundreds of millions of each state design were struck for general circulation, making them extremely common. That said, it’s worth examining it closely under magnification for any errors such as doubling, off-center strikes, or unusual coloring, as those can dramatically increase value.

4. What mint marks should I look for, and where are they located?

Look just below the “In God We Trust” motto on the obverse. A “P” means it was struck in Philadelphia, “D” in Denver, and “S” in San Francisco. San Francisco coins were made exclusively for collectors as proof issues and were never released into general circulation, making them considerably scarcer than their P and D counterparts.

5. Why do Georgia and Connecticut quarters tend to sell for more than other 1788 quarters?

Both were released in 1999 — the first year of the program — when public enthusiasm was at its peak. Early releases attracted the most collector attention and investment, and that momentum has held up at auction decades later. Being first mattered more than being plentiful, and both states still command premiums that later issues struggle to match.

6. What makes the Massachusetts quarter so valuable compared to other 2000 issues?

A Denver-minted Massachusetts quarter graded PCGS MS-69 holds the record for the highest price ever paid for a business-strike 2000 state quarter, reaching $9,000 at auction. Part of its appeal lies in its unique origin story — the reverse design was created by schoolchildren, not professional artists — which gives it a sentimental distinction that resonates with collectors.

7. The New Hampshire quarter shows a rock formation — is that formation still standing today?

No. The Old Man of the Mountain, the granite profile depicted on the reverse, collapsed due to natural erosion in May 2003 — just three years after the coin entered circulation. That event turned the quarter into an unofficial memorial, and many people began actively seeking it out as a keepsake. It now shares with the Connecticut quarter the distinction of depicting a landmark that no longer exists.

8. How do silver proof versions differ from the regular clad quarters, and are they more valuable?

Silver proof versions were struck at the San Francisco Mint exclusively for collector sets. They contain 90% silver and 10% copper, compared to the standard copper-nickel clad composition. They also feature sharper, mirror-like finishes. Because of their limited mintage and precious metal content, they consistently sell for more than their clad counterparts — often significantly more for top-grade examples.

9. What is the single most valuable 1788 quarter error ever sold?

The Mule Error holds that title by a wide margin. Only about 19 examples are known to exist, each combining the Sacagawea dollar’s reverse with a state quarter obverse — two entirely different coin designs that were never meant to share the same planchet. One example sold for $192,000 in 2018, making it the most sought-after error in the entire State Quarters series.

10. Is it worth paying for professional grading on my 1788 quarter?

Only if your coin has a realistic chance of being worth significantly more than the grading fee. For standard circulated examples, professional grading simply doesn’t make financial sense. However, if your coin appears to be in flawless uncirculated condition, shows a dramatic and clearly documented error, or you’re planning to sell through a major auction house, then certification can substantially increase buyer confidence — and the final sale price.
