2016 Quarter Value (2026 Guide): Errors List, “D”, “S” & “P” Mint Mark Worth

Circulated 2016 quarters typically trade at their twenty-five cent face value. Condition is the single biggest factor separating a pocket-change coin from one worth hundreds of dollars.

The 2016 quarter value can jump dramatically with higher Mint State (MS) grades — a standardized numerical scale from 1 to 70 used by professional grading companies to describe a coin’s condition. A 2016-D Shawnee quarter leaps from $0.25 in worn condition all the way to $1,800 at the top of the MS68 grade, while a Theodore Roosevelt example commands $1,020 in similar preservation.

These five releases marked the seventh year of the America the Beautiful (ATB) Quarters Program — a series honoring national parks and historic sites across the United States. Understanding what separates ordinary finds from valuable specimens helps collectors identify worthwhile additions to their collections.

Top 10 Most Valuable 2016 Quarter Worth Money

The 2016 quarter series shows notable value variations among high-grade specimens. The 2016-D Shawnee leads the auction record list at $1,800 for an MS68 example sold on eBay in 2021, followed by Fort Moultrie coins from both Denver and Philadelphia mints.

A clear value gap exists between the upper and lower portions of this ranking. The first five coins all exceed $1,000, while the bottom six fall below $600.

Grade 68 specimens dominate this list, appearing in eight of ten positions. One grade 67 Shawnee still reached $400, while a grade 70 Harpers Ferry sits at the bottom with just $325 — proving that design and mint mark can matter more than small differences in numerical grade.

The data reflects market activity from 2018 to the present. Collector interest in the “MS-68 Wall” — the dramatic price jump that occurs at the MS68 grade level due to consistent production quality issues — continues to drive premium prices for pristine examples of all five 2016 designs.

 

History of The 2016 Quarter

The America the Beautiful Quarters Program launched in 2010 as the successor to the highly popular 50 State Quarters Program. It was authorized by Public Law 110-456, signed in 2008, under the official title “America the Beautiful National Parks Quarter Dollar Coin Act of 2008.”

The 2016 releases came at the program’s midpoint — the 31st through 35th issues in the 56-coin series. Mintages across the program stabilized in 2016 and 2017 after a huge surge in 2015 when nearly 3 billion quarters were produced.

These quarters were minted during President Barack Obama’s second term in office. The nation was experiencing continued economic recovery following the 2008–2009 financial crisis, and consumer confidence was gradually improving.

The five sites honored on 2016 quarters carried deep historical significance. Cumberland Gap served as a critical gateway for westward expansion in the late 18th century — the inscription “DOORWAY TO THE WEST” appears on the coin’s reverse. Harpers Ferry marked the location of John Brown’s famous 1859 raid, a pivotal event that intensified pre-Civil War tensions across the nation.

The program honored sites in chronological order based on when each location was officially established as a national site. This ongoing approach helped raise public awareness of America’s diverse natural and cultural heritage for millions of Americans who encountered these quarters in everyday circulation.

In 2016, the U.S. Mint also released a special 24-karat gold Standing Liberty quarter to mark the 100th anniversary of Hermon A. MacNeil’s original 1916 design. That commemorative piece — bearing the West Point “W” mint mark — was limited to 100,000 coins, with final reported sales of 91,752, making it a completely separate and highly valuable collector item beyond the ATB series.

Is Your 2016 Quarter Rare?

For detailed rarity information and current market values of specific 2016 America the Beautiful quarters, the CoinValueChecker App provides comprehensive data to help collectors assess their coins accurately.

 

Key Features of The 2016 Quarter

The 2016 quarters represent the seventh year of the multi-year program honoring national parks and sites. Five distinct designs were released throughout the year, each celebrating significant locations across the United States.

These quarters maintain the standard specifications of the series while featuring unique reverse designs that showcase America’s natural beauty and historical heritage.

The Obverse Of The 2016 Quarter

The obverse design remains consistent across all 2016 quarters, featuring the restored 1932 portrait of George Washington by sculptor John Flanagan. Flanagan’s initials “JF” are visible at the base of the bust truncation on close inspection. This right-facing profile of the first president appears on all America the Beautiful issues.

The inscription “UNITED STATES OF AMERICA” curves along the top edge, while “QUARTER DOLLAR” is positioned at the bottom. The motto “LIBERTY” appears to the left of Washington’s portrait, and “IN GOD WE TRUST” is inscribed to the right, following the standard format established for the entire ATB series.

The Reverse Of The 2016 Quarter

There are five different reverse designs in the 2016 series, each created by U.S. Mint Artistic Infusion Program (AIP) artists and engraved by Mint staff sculptors.

The Shawnee National Forest quarter depicts Camel Rock rising from the Garden of the Gods recreation area, with a red-tailed hawk soaring overhead. The design was created by AIP artist Justin Kunz and engraved by Jim Licaretz for the February 2016 release honoring Illinois’s diverse wilderness.

Cumberland Gap National Historical Park shows a frontiersman gazing westward across the Cumberland Mountains, with the inscription “DOORWAY TO THE WEST” on his left. Joseph Menna designed this April 2016 quarter honoring Kentucky’s famous gateway to western expansion.

Harpers Ferry National Historical Park displays John Brown’s Fort, the firehouse building where the famous 1859 abolitionist raid took place. Thomas Hipschen created the design and Phebe Hemphill sculpted the dies for this West Virginia site released in June 2016.

Theodore Roosevelt National Park presents the 26th president on horseback near the Little Missouri River, surveying the Badlands landscape. Joel Iskowitz’s design — selected from six candidate submissions reviewed by park representatives — was sculpted by Phebe Hemphill for this August 2016 release.

Fort Moultrie depicts Sergeant William Jasper heroically raising South Carolina’s fallen regimental flag — the crescent moon later featured on the state’s flag — during the 1776 British assault on Fort Sullivan. Joseph Menna designed this November 2016 release.

Other Features Of The 2016 Quarter

The 2016 quarters maintain standard specifications for all America the Beautiful coins. Each quarter measures 24.26 millimeters in diameter and weighs 5.67 grams, with a thickness of 1.75 millimeters.

The composition consists of a copper core clad with an outer layer of cupro-nickel — 75% copper and 25% nickel — bonded to a pure copper center. This clad composition has been standard for circulating quarters since 1965. The edge features 119 reeds, the traditional reeded edge pattern used on quarters since 1796 that also helps with authentication.

2016 Quarter Value — Mintage & Survival Data

The Philadelphia Mint struck five 2016 quarter designs with varying mintage numbers. Mintages across the ATB program stabilized in 2016 and 2017 after a huge spike in 2015, reflecting more measured Federal Reserve ordering.

Harpers Ferry leads significantly at 434,630,000 coins, nearly double any other 2016 design. Theodore Roosevelt ranks second at 231,600,000, followed by Cumberland Gap at 215,400,000.

Shawnee and Fort Moultrie occupy the lower end at 155,600,000 and 154,400,000 respectively. The combined Philadelphia and Denver mintage for Cumberland Gap reached a combined total of 440,838,338 pieces — the highest combined figure for any 2016 design.

The San Francisco Mint produced collector-only editions for all five designs: approximately 5,146,840 uncirculated business strikes, 3,492,979 clad proofs, and 2,576,160 silver proofs per design. San Francisco’s S-mint business strikes are sold directly to collectors, never entering general circulation.

The Easy Way to Know Your 2016 Quarter Value

Determining your 2016 quarter’s value requires examining several key factors. Check the coin’s condition, noting any wear or damage on the surfaces, then identify the mint mark on the obverse — P for Philadelphia, D for Denver, or S for San Francisco.

Look for any striking errors or unusual characteristics that might increase value. Compare your coin’s grade against the standard Sheldon Scale (1–70), originally developed by Dr. William H. Sheldon and now used by professional grading services like PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company).

The CoinValueChecker App simplifies this evaluation process by providing comprehensive assessment tools and current market data for accurate 2016 quarter valuations.

 

2016 Quarter Value Guides

The 2016 America the Beautiful quarter series consists of five distinct releases, each with varying value potential in the numismatic market. Collectors seek high-grade examples, proof strikes, and special silver editions from this year.

Circulation strikes from Philadelphia and Denver mints form the base of most collections, while proof versions from San Francisco carry additional premiums.

The five quarters released in 2016 include:

• 2016 Shawnee Quarter — First release with strong collector demand for proofs and MS68 specimens
• 2016 Cumberland Gap Quarter — Mid-year issue with the highest combined P+D mintage among 2016 releases
• 2016 Harpers Ferry Quarter — Highest single-mint circulation figures; noted for Denver die-quality variations
• 2016 Theodore Roosevelt Quarter — Features scarce Prooflike (PL) variants from the Denver Mint
• 2016 Fort Moultrie Quarter — Final 2016 release; a Denver MS68 Premium Quality example achieved $1,495

Each quarter’s value depends primarily on condition grade and format. Uncirculated specimens command higher prices than circulated examples. Proof and silver proof versions typically exceed circulation strike values. Professional grading by PCGS or NGC significantly impacts market pricing for premium examples.

Important note for collectors: colorized or gold-plated 2016 quarters sold online are private post-mint alterations with no numismatic value — authentic U.S. Mint-issued coins are never colorized or plated after leaving the Mint.

 

2016 Shawnee Quarter Value

The 2016 Shawnee Quarter is the 31st issue in the entire America the Beautiful series. It features Camel Rock rising from the Garden of the Gods recreation area in Shawnee National Forest, Illinois, a sandstone formation that draws approximately 150,000 visitors annually.

Grade determines value dramatically. A PCGS MS68 example commanded $1,800 on eBay in 2021, while an MS67 specimen sold for $44.95 as recently as August 2025 — revealing how quickly value drops below the prized MS68 level. According to population data from CoinWeek (September 2025), only one PCGS MS68 and two NGC MS69 examples have been certified at those respective services, establishing genuine scarcity at the top grades.

Among proof editions, silver PR70DCAM (Deep Cameo — meaning frosted designs against mirror-like fields) pieces reached $105 in March 2018, compared to standard clad PR70DCAM versions at $70 the previous month. Collectors should also watch for die chip errors visible on Camel Rock and a documented die break between the hawk’s wing and tail — both uncirculated examples typically fetch $1 to $5 above standard value.

Collectors seeking the finest pieces should focus on early die state examples, which retain sharper geological detail on the rock surface. Three-coin sets from Philadelphia, Denver, and San Francisco allow for direct comparison of strike quality across mints.

The accompanying chart illustrates this quarter’s market activity over the past year.

 

2016 Cumberland Gap Quarter Value

The 2016 Cumberland Gap Quarter honors one of America’s most historically significant passages. Used by thousands of settlers moving into Kentucky and the interior frontier during the late 18th century, the gap symbolized opportunity, risk, and westward ambition — all captured in Joseph Menna’s frontiersman design.

Philadelphia and Denver struck a combined 440,838,338 circulation quarters, while San Francisco produced collector-only editions. MS65 specimens typically value around $8, though MS67 examples command $135, revealing how scarce truly pristine strikes remain despite the enormous mintage.

Every 2016 variant qualifies for the First Strike designation when submitted to a grading service within thirty days of the Mint’s official release date. First Strike proofs consistently achieve PR69–70 grades. Clad versions trade for $18–$30, while silver proofs reach $15–$35 in those grades — a modest spread that reflects the inherent superiority of San Francisco’s proof production process.

The PCGS price guide value of $0.40 for the lowest circulated grades reminds collectors that condition still rules all valuation. Only MS68 and above examples are worth the cost of professional grading at current certification fees.

The following chart documents this quarter’s market performance throughout recent months.

 

2016 Theodore Roosevelt Quarter Value

Joel Iskowitz’s design — chosen from six candidate submissions after review by park representatives, advisory committees, and the Commission of Fine Arts — shows young Roosevelt on horseback surveying Little Missouri River terrain. The Badlands landscape where he ranched in the 1880s directly shaped his later conservation policies as president, making this design both historically rich and visually compelling.

Auction records reveal striking mint disparities. Philadelphia MS68 specimens reached $1,020 at Heritage Auctions in February 2018, while Denver MS68 examples brought $500 three months later. The D-mint MS68 also shows a notable market split: the NGC Price Guide lists it around $100, while PCGS-graded examples have reached $500 at auction — suggesting buyers pay a meaningful premium for PCGS certification at this grade level.

Denver strikes occasionally display Prooflike (PL) surfaces — mirror-like fields that result from freshly polished dies, requiring clear reflections visible from 2–4 inches for certification. MS66PL pieces command approximately $40, while MS68PL examples achieved $345 in 2023. Only single MS68PL and MS69PL specimens are known to be certified, establishing genuine scarcity. The Theodore Roosevelt silver proof also shows significant value divergence in PR70DCAM: NGC lists $32.50, while PCGS-graded examples have achieved $104.50 at auction.

Market patterns over recent twelve months provide additional context for valuation.

 

2016 Harpers Ferry Quarter Value

Thomas Hipschen’s design was selected from eight candidate submissions reviewed by park representatives, advisory committees, and the Commission of Fine Arts before Treasury approval. Sculptor Phebe Hemphill created the dies depicting John Brown’s Fort — the firehouse where abolitionist John Brown staged his 1859 raid on the Harpers Ferry Armory, intensifying national slavery tensions on the eve of the Civil War.

Harpers Ferry had the highest single-mint Philadelphia circulation figure in the 2016 series at 434,630,000 coins, yet high mintage has not translated into top-grade availability. Both the Philadelphia and Denver MS65 examples are worth around $0.80 in that grade, rising to approximately $16 at MS67 — a level where pristine strikes remain genuinely scarce. A 2016-D West Virginia quarter with a die clash error graded MS63 sold for $100 at a 2020 eBay auction, and a 2016-D Harpers Ferry MS61 with doubled die error brought $85 in 2019.

San Francisco produced two proof variants: standard copper-nickel clad and 90% silver compositions. Identifying them is straightforward — silver proofs weigh 6.30 grams versus clad’s 5.67 grams, and the edge of clad quarters displays visible copper core striping while silver quarters maintain uniform silvery-gray coloring throughout.

The recent one-year market activity chart highlights current collector interest and value trends for this issue.

 

2016 Fort Moultrie Quarter Value

The 2016 Fort Moultrie Quarter depicts Sergeant William Jasper heroically returning South Carolina’s fallen regimental flag — the crescent later incorporated into the state flag — during the 1776 British assault on Fort Sullivan. Joseph Menna’s design makes this one of the most historically evocative reverses in the entire ATB series.

A Denver MS68 specimen achieved $1,495 due to the convergence of several rare factors: Premium Quality designation indicating exceptional eye appeal beyond typical MS68 standards, MAC (Metadata Accreditation Corporation) registry recognition, Finest Grade status, and a certified population of only six examples at that level. Current market data shows Denver examples at MS68 trading around $450. Philadelphia and Denver MS67 examples share identical auction records — $299 in 2022 — establishing clear grade-based pricing tiers for this design.

Denver also produced scarce Prooflike (PL) variants with mirror-like fields, just as the Theodore Roosevelt Denver issue does. Fort Moultrie quarters are common in circulation, but gem-quality mint state examples are genuinely scarce — even extensive bank roll searches rarely yield top-grade coins, making certified high-grade pieces especially prized by registry set collectors.

Market activity over the past year reflects continuing demand, with increased attention on premium-certified coins.

Rare 2016 Quarter Error List With Values

The 2016 America the Beautiful quarter series has produced several collectible mint errors. These mistakes during the manufacturing process create variations that attract numismatists seeking rare specimens beyond standard circulation strikes.

1. Doubled Die Obverse (DDO) Errors

The 2016 ATB quarters exhibit doubled die errors primarily on Washington’s portrait and the inscriptions. A doubled die (DDO — Doubled Die Obverse) occurs when a die receives multiple impressions during the hubbing process, with slight misalignment between strikes creating a ghosted doubling effect on the final coin.

Collectors should examine “IN GOD WE TRUST” and Washington’s eye details under magnification. In 2019, a 2016-D Harpers Ferry quarter graded MS61 with a doubled die error sold for $85, while the Theodore Roosevelt design shows particularly notable DDO characteristics on the obverse lettering. Circulated specimens with pronounced doubling can command 150–400% above face value, with uncirculated examples fetching significantly more.

2. Off-Center Strike Errors

An off-center strike is one of the most visually dramatic errors in the Washington quarter series. It occurs when the planchet is not properly centered in the collar when the die strikes, causing the design to shift toward one edge and leaving a crescent of blank metal on the opposite side.

In 2017, a collector paid $265 for a 2016-P North Dakota (Theodore Roosevelt) ATB quarter with an off-center strike error. Values increase with the degree of off-centering — a 30% off-center is more valuable than a 10% version — and coins that still show a complete, readable date despite the offset command the highest prices.

3. Struck-Through Grease Errors

Manufacturing debris causes struck-through errors when foreign material — most commonly die lubricating grease — prevents complete contact between the die and the planchet. For 2016 ATB quarters, grease strikes most frequently affect the intricate reverse design details. Landscape elements, architectural details, and inscriptions may appear faint, partially missing, or completely obliterated where grease blocked proper metal flow.

The Cumberland Gap design can suffer particularly from this error type, with the natural arch formation and surrounding mountain landscape becoming partially obscured. Severe struck-through errors where major design elements disappear attract far more collector interest, with values ranging from $25 to several hundred dollars depending on which design areas are affected.

4. Die Crack and Die Cud Errors

Progressive die deterioration creates raised crack lines on struck coins where the die metal has fractured under repeated striking pressure. The 2016 Harpers Ferry quarter shows documented die cracks affecting the John Brown’s Fort representation. Minor die cracks add modest premiums of $5–$15 over standard value.

Die cuds — the more advanced failure stage where metal fragments separate from the die face and create raised blobs on finished coins — are worth considerably more. The Fort Moultrie design has documented major die breaks affecting the fort’s defensive walls and palmetto tree imagery. Major cuds removing significant design portions can reach $100–$300 depending on the size and location of the affected area.

5. Wrong Planchet and Clipped Planchet Errors

A wrong planchet error occurs when quarter dies strike a planchet intended for a different denomination. A rare 2016-D Theodore Roosevelt quarter struck on a nickel planchet graded MS62 sold for $500 at an eBay auction in 2021 — one of the most valuable 2016 error coins documented. A wrong-planchet quarter on a nickel planchet will be smaller (about 21.2mm vs. the standard 24.26mm), lighter (5 grams vs. 5.67 grams), and the design will not reach the coin’s rim.

Clipped planchet errors occur when the metal strip is misaligned during the blanking process, causing the coin blank to be partially cut away before striking. A statehood-era quarter with a single curved clip is worth roughly $50–$60; a triple clip can reach $100–$150. In 2017, Heritage Auctions sold a 2016-P MS60 West Virginia (Harpers Ferry) quarter with a missing clad layer and improperly annealed error for $150. Always be aware that clipped planchets can be faked — a genuine clip will show metal flow into the clipped area rather than a sharp cut edge.

6. Die Cap Errors

A die cap error occurs when a struck coin sticks to the hammer die face and is not ejected. That coin’s reverse then becomes the new face of the hammer die, impressing a ghost image of the design onto subsequent coins fed into the press. A 2016-P Harpers Ferry quarter graded MS63 with a die cap error sold for $130 at a Heritage Auctions sale in 2020. Die cap errors on ATB quarters are genuinely scarce and represent the most visually complex errors in this series.

FAQ About 2016 Quarter Value

1. Which 2016 quarter design has the highest recorded sale price?

The 2016-D Shawnee Quarter holds the top auction record at $1,800 for an MS68 specimen sold on eBay in 2021.

Fort Moultrie from Denver reached $1,495 due to its Premium Quality designation and a certified population of only six MS68 examples, while the Theodore Roosevelt Philadelphia MS68 brought $1,020 at Heritage Auctions in February 2018.

2. What makes 2016 quarters valuable to collectors?

Grade is the primary value driver, with the dramatic jump at MS68 — called the “MS-68 Wall” — generating the biggest price differences in this series.

Special varieties add further value: Denver Prooflike (PL) strikes with mirror-like surfaces are scarce, and silver proofs with Deep Cameo (DCAM) contrast — frosted devices against mirror-like fields — are highly sought by registry set collectors.

3. What is the difference between clad and silver proof 2016 quarters?

Clad proofs contain a copper-nickel composition and weigh 5.67 grams; silver proofs are struck in 90% silver and weigh 6.30 grams. Both feature mirror-like fields and frosted designs.

Edge inspection provides quick identification — clad shows visible copper core striping, while silver displays uniform silvery-gray coloring. Sound testing also works: a silver quarter produces a higher-pitched ring when dropped compared to a clad coin’s duller tone.

4. Which 2016 quarter has the lowest mintage, and does that make it more valuable?

Fort Moultrie has the lowest Philadelphia mintage at 154,400,000 coins, and Theodore Roosevelt had a combined P+D mintage of approximately 463,200,000. However, low mintage alone does not guarantee high value for modern ATB quarters.

What actually drives value at the MS68 level is condition rarity — the difficulty of finding a pristine example — not just mintage figures. The S-mint business strike has a much smaller mintage than the D-mint version yet can trade at similar MS68 prices, demonstrating that grade scarcity matters more than production numbers.

5. Are 2016 quarter errors rare, and what are the most valuable ones?

Major errors on 2016 ATB quarters are genuinely rare due to improved mint quality control after 2002. The most valuable documented example is a 2016-D Theodore Roosevelt quarter struck on a nickel planchet (wrong planchet error), which sold for $500 graded MS62.

Other notable errors include die cap errors ($130 for an MS63 Harpers Ferry example at Heritage in 2020), off-center strikes ($265 for a 2016-P North Dakota ATB quarter in 2017), and missing clad layer errors ($150 at Heritage in 2017 for a Harpers Ferry example).

6. What is a Prooflike (PL) 2016 quarter and why is it valuable?

A Prooflike (PL) designation is awarded by grading services to circulation-strike coins that display mirror-like fields normally associated with proof coins. PL surfaces arise from freshly polished dies at the start of a new die run and must show clear reflections from 2–4 inches to qualify for the designation.

For 2016 quarters, Denver produced documented PL examples for the Theodore Roosevelt and Fort Moultrie designs. A Theodore Roosevelt MS68PL sold for $345 in 2023, and with only single MS68PL and MS69PL specimens certified, these are among the rarest 2016 quarter varieties available.

7. Should I get my 2016 quarter professionally graded?

Professional grading by PCGS or NGC is cost-effective only when your coin appears to be at the MS68 level or above (potential value $100–$1,800), an S-mint business strike in apparent MS67 or better, a proof that appears PR70DCAM, or a confirmed error coin.

Do not submit common P- or D-mint quarters that appear to grade MS67 or lower — standard grading fees of $20–$30 per coin would exceed the coin’s market value, resulting in a net loss.

8. Does the 2016 gold Standing Liberty quarter count as part of the 2016 ATB series?

No — the 2016 gold Standing Liberty quarter is a separate commemorative coin issued for the 100th anniversary of Hermon A. MacNeil’s 1916 design. It was struck in 24-karat (.9999 fine) gold at the West Point Mint, the first U.S. quarter to bear the “W” mint mark, and was limited to 100,000 pieces with final sales of 91,752.

This coin has a melt value floor of approximately $1,016.80 at recent gold prices and trades at substantial premiums above that, placing it in an entirely different value category from the standard ATB clad and silver quarters.

9. How do I tell a genuine 2016 proof quarter from a business strike?

Genuine San Francisco proof quarters feature sharp, mirrored fields with frosted, raised design devices — a result of specially polished dies and multiple strikes at slower press speeds. Business strikes from Philadelphia and Denver have a normal satin or satiny luster rather than mirror-like surfaces.

Under a magnifier, a proof coin’s fields will reflect your image clearly, like a mirror, while a business strike will appear grainy or matte by comparison. If the coin is in an original U.S. Mint proof set packaging, that packaging is the most reliable confirmation of proof status.

10. What happened to the America the Beautiful Quarters Program after 2016?

The program continued releasing five new designs per year through 2021, completing all 56 state, district, and territory issues. After the program ended, it was followed by the American Women Quarters Program, which ran from 2022 through 2025 and honored pioneering American women on quarter reverses.

The complete 2010–2021 ATB set now represents a finished, collectible series, which typically increases long-term collector interest. High-grade MS68 examples of 2016 and other mid-series years continue to appreciate as the pool of ungraded, high-quality inventory is gradually absorbed by the market.
