Silver proof coins dominate the upper tier. The Delaware, Georgia, and New Jersey silver proofs all appear in the top rankings. Their 90% silver content combined with perfect PR70 grades creates significant collector demand.

Philadelphia-minted business strikes also achieve substantial prices. Pennsylvania quarters appear three times in different grades, ranging from $2,640 to $10,200. Georgia appears twice, with values between $2,875 and $4,200. This spread demonstrates how grade differences translate to price variations.

History of The 1999 Quarter

Congress authorized the 50 State Quarters Program in 1997 through Public Law 105-124. President Bill Clinton signed the legislation on December 1, 1997. Republican Representative Mike Castle of Delaware championed the bill through Congress.

It launched on January 4, 1999, with Delaware’s quarter entering circulation. This marked the beginning of a ten-year series designed to honor each state.

The release schedule followed the order in which states ratified the Constitution or joined the Union. Five quarters appeared each year, with each design circulating for approximately ten weeks.

Delaware led as the first state to ratify the Constitution in 1787. Pennsylvania, New Jersey, Georgia, and Connecticut followed in 1999.

The cultural climate of 1999 favored the program’s launch. As the nation approached the millennium with optimism, Americans sought connections to their heritage. The quarters served as both educational tools and accessible collectibles.

The program transformed coin collecting: an estimated 147 million people—about half the population—participated, generating roughly $3 billion as collectors removed coins from circulation.

Key Features of The 1999 Quarter

The 1999 quarters represent the inaugural year of the 50 State Quarters Program, introducing five distinct designs that honor Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut.

All five coins share a common obverse design featuring George Washington, while each reverse showcases unique state-specific imagery.

The Obverse Of The 1999 Quarter

The obverse displays a modified portrait of George Washington designed by William Cousins, based on John Flanagan’s original 1932 design. This updated rendering was created specifically for the State Quarters Program to accommodate relocated inscriptions.

“UNITED STATES OF AMERICA” appears in a semi-circular arrangement above Washington’s head. The word “LIBERTY” sits to the left below his chin, while “IN GOD WE TRUST” appears to his right. The denomination “QUARTER DOLLAR” curves along the bottom rim beneath Washington’s bust.

The mint mark (P for Philadelphia, D for Denver, or S for San Francisco) is positioned to the right of Washington’s ponytail. This redesigned obverse was necessary because inscriptions traditionally placed on the reverse were moved to the front, allowing full canvas space for state designs on the back.

The Reverse Of The 1999 Quarter

All reverses include the state name, ratification year (1787 or 1788), minting year (1999), and the motto “E PLURIBUS UNUM”.

Delaware Quarter: Caesar Rodney on horseback commemorates his historic ride to Philadelphia to cast the deciding vote for independence. The inscription “THE FIRST STATE” appears alongside his name.

Pennsylvania Quarter: The Commonwealth statue from Pennsylvania’s State Capitol dome stands at center, with a keystone symbol representing the state’s nickname. The words “VIRTUE LIBERTY INDEPENDENCE” surround these elements.

New Jersey Quarter: George Washington crosses the Delaware River with his troops in 1776. The phrase “CROSSROADS OF THE REVOLUTION” below the scene acknowledges New Jersey’s strategic role during the Revolutionary War.

Georgia Quarter: A peach sits at center, surrounded by Live Oak sprigs forming a circular frame. The state motto “WISDOM JUSTICE MODERATION” appears between the branches, with the state outline visible behind.

Connecticut Quarter: The Charter Oak tree dominates the design, its branches spreading across the coin’s face. The caption “THE CHARTER OAK” identifies the tree that legend says hid Connecticut’s charter from British authorities in 1662.

Other Features Of The 1999 Quarter

The standard circulation quarters feature a copper-nickel clad composition. The outer layers consist of 75% copper and 25% nickel, bonded to a core of pure copper. This creates an overall composition of 91.67% copper and 8.33% nickel.

Special silver proof quarters were also produced with 90% silver and 10% copper composition. These proof versions were struck exclusively at the San Francisco Mint for collector sets.

The clad quarters weigh 5.67 grams, while silver proof versions weigh 6.25 grams. Each coin measures 24.26 millimeters in diameter and 1.75 millimeters in thickness.

The edge contains 119 reeds, maintaining the traditional reeded design used on quarters since 1796. This security feature helps distinguish genuine coins from counterfeits and was originally implemented when quarters contained precious metal.

1999 Quarter Mintage & Survival Data

Philadelphia struck significantly different quantities across the five 1999 state quarters.

Connecticut received the highest mintage at 688,744,000 coins, while Pennsylvania had the lowest at 349,000,000. Delaware, New Jersey, and Georgia fell between these extremes, with Georgia reaching 451,188,000 pieces.

All five designs maintain an identical 75% survival rate, indicating approximately one quarter of each issue has left active circulation. This uniform pattern applies regardless of whether the original mintage was relatively modest like Pennsylvania or exceptionally large like Connecticut.

The data reflects coins struck only at the Philadelphia Mint, representing roughly half of the total 1999 state quarter availability when Denver Mint strikes are included.

The Easy Way to Know Your 1999 Quarter Value

Start by locating the mint mark (P, D, or S) below “IN GOD WE TRUST”. The coin’s surface reveals its condition—check for wear patterns and luster quality. Striking errors like off-center designs can significantly increase value. Silver proofs weigh more than standard quarters, providing an easy verification method.

The CoinValueChecker App simplifies this entire process. Photograph your quarter, and the app instantly identifies the mint mark, analyzes condition grade, detects errors, and provides current market values—delivering accurate results in seconds.

1999 Quarter Value Guides

The five 1999 state quarters range dramatically in value based on condition grade and mint mark. High-grade specimens certified MS67 or above reach hundreds to thousands of dollars at auction.

Silver proof versions from San Francisco carry additional value due to their 90% silver content and limited availability. The first-year status of these coins adds collector appeal, particularly for pristine examples. Condition remains the primary value driver across all five designs.

The program released these quarters in constitutional ratification order:

1999 Delaware Quarter Value

The 1999 Delaware Quarter opens the 50 State Quarters series, honoring Delaware as the first state to ratify the Constitution. Its reverse depicts Caesar Rodney’s seventy-mile horseback ride on July 1, 1776, securing Delaware’s decisive vote for independence.

Philadelphia’s issue stands apart. In addition to standard business strikes, it alone produced a prooflike version—making Delaware the only 1999 state quarter with a mirror-like surface from the Philadelphia Mint.

This distinction drives a sharp value gap: an MS66 business strike trades for $12–$14, while the prooflike example commands around $150.

At the top of the market sits the silver proof edition from San Francisco. It ranks first in the entire Washington 50 State Quarters series, highlighted by a PR70 example that sold for $17,250 at Heritage Auctions on December 4, 2007.

For collectors, priority should go to crisp strike quality—Rodney’s posture, the horse’s stride, and the state outline. In high grades, patience is often rewarded with lasting appreciation.

The complete auction history reveals this coin’s market evolution.

Meanwhile, recent twelve-month market patterns illustrate current collector demand.

1999 Pennsylvania Quarter Value

Pennsylvania’s reverse centers on the Commonwealth statue, which has crowned the capitol dome since 1905—her raised right arm symbolizing mercy, her left holding a ribbon mace for justice.

Paired with the keystone emblem of Pennsylvania’s Civil War significance, the design distills monumental sculpture into miniature numismatic storytelling.

Each design in this series follows the three-mint standard: Philadelphia and Denver produced circulation strikes, while San Francisco focused exclusively on proof coins with their distinctive mirror-like finish.

High-grade circulation coins command remarkable premiums. At MS67, Philadelphia examples reach $35 while Denver specimens climb to $125.

The gap widens dramatically at MS68: Philadelphia pieces valued at $1,350 pale beside Denver’s extraordinary $8,750. Fewer Denver coins have achieved this elite grade, despite comparable overall survival rates.

Condition sensitivity trumps mintage figures in determining value—a lesson this coin teaches decisively.

Detailed auction performance data spanning multiple years shows how condition rarity drives these numbers.

Meanwhile, recent market trends illustrate shifting collector interest of this quarter.

1999 New Jersey Quarter Value

New Jersey earned its title as the “Crossroads of the Revolution” through hard reality, hosting more battles than any other colony. The quarter shows Washington’s 1776 Christmas crossing, whose Trenton victory gave the Continental Army its first decisive win and turned New Jersey into the war’s turning point.

Premium circulation strikes currently range from $2,150 to $8,850 depending on mint facility. San Francisco produced proof versions in both standard clad and silver compositions, each bearing the Deep Cameo designation.

Dies received additional polishing between strikes, with blank planchets hand-fed to achieve the signature frosted devices against glassy fields.

The clad proof market peaked at $500 for a PR69 specimen in 2004. Silver proofs substantially outperformed: a flawless PR70 example realized $2,530 in 2007, establishing the format’s ceiling.

Authentication hinges on edge examination—silver proofs display uniform metallic luster across their reeded edges, while clad versions reveal copper layers. Weight provides secondary confirmation at 6.30 grams versus 5.67 grams for clad.

Complete sale histories spanning two decades reveal how grade sensitivity evolved.

Current market patterns demonstrate persistent collector preference for proof examples across all grade levels.

1999 Georgia Quarter Value

Georgia ratified the Constitution on January 2, 1788, becoming the fourth state—a status reflected in this quarter’s reverse. The peach and live oak symbolize the agricultural economy that underpinned early statehood, while the motto “Wisdom, Justice, Moderation” echoes the principles Georgia’s delegates championed during the constitutional debates

The Mint released this quarter on July 19, 1999, midway through summer when collectors had already embraced the program’s momentum.

Unlike Delaware’s debut ceremony, Georgia’s launch occurred with established protocol—banks distributed rolls while numismatic dealers positioned inventory for the anticipated demand.

At MS68, Philadelphia examples command roughly $5,500 in current markets, with only 5 coins certified by PCGS at this grade and none higher. Denver quarters reach $6,250, where 3 specimens hold MS68 status alongside a single MS69—the format’s finest known example.

Proper storage requires non-PVC holders in stable, low-humidity environments. Temperature fluctuations accelerate toning that diminishes eye appeal and grade.

Here are the historical auction records for this coin across different grades which can help you have a clear understanding of its value.

Market patterns over recent months provide additional context for valuation.

1999 Connecticut Quarter Value

Connecticut’s 1662 Royal Charter granted rare self-governance, defied in 1687 when Joseph Wadsworth hid it in the Charter Oak to block its seizure.

When the state ratified the Constitution in 1788, that charter remained its constitution until 1965, making this quarter a tribute to America’s longest-serving founding document.

Like the Delaware issue, Philadelphia’s production has reached MS69 with a single known specimen, which has held a $10,500 valuation since 2021. The effect of grade becomes clear at MS67, where a Heritage Auctions result of $4,362 establishes benchmarks for the wider population.

Top-grade circulation strikes remain frustratingly scarce for specialists pursuing completion. Silver proofs offer accessible alternatives, trading between $10 and $55 depending on certification level. One PR70 specimen was sold at $1,610.

Scarcity at premium grades, combined with the design’s historical resonance as the series’ final 20th-century release, positions this issue favorably against evolving collector priorities.

For those tracking realized prices, the complete auction history offers a window into how buyers have valued this issue since release.

The next chart shows its market trends and activity over the past twelve months.

Rare 1999 Quarter  Error List

The 1999 Washington 50 States Quarters series launched a decade-long program that captured collectors’ attention nationwide. Among these inaugural coins, several minting errors emerged that transformed ordinary pocket change into numismatic treasures worth substantial premiums today.

1. Die Crack Errors

This error earned its nickname from a raised die crack extending from Caesar Rodney’s horse’s mouth downward through the letter “C” in “Caesar” on 1999-P Delaware quarters.

The flaw occurred when the striking die developed a crack during production, causing metal to fill the void and create a distinct raised line on finished coins. Early strikes from the worn die show clearer definition.

Market values range from $3 to $20 for circulated examples, with uncirculated specimens reaching $40 or more. Professional grading services have certified numerous examples, with MS65 grade coins occasionally exceeding $50 when the crack is particularly bold and visible.

2. Doubled Die Reverse (DDR) Errors

This variety appears on 1999-P Connecticut quarters, showing duplicated design elements in the Charter Oak’s branches on the reverse.

The doubling results from die misalignment during production, creating a subtle shadow effect in specific branch sections on the tree’s right side. Identification requires magnification as the effect is relatively subtle. Some examples additionally show minor doubling in reverse lettering.

Most circulated specimens with clear doubling trade for $10 to $25. Sharp uncirculated examples can reach higher premiums among specialist collectors. The variety doesn’t enjoy widespread recognition compared to the Delaware die crack, keeping prices moderate while additional examples continue surfacing in circulation.

3. Wrong Planchet Errors (Experimental Planchet)

The U.S. Mint tested golden alloys for the upcoming Sacagawea dollar program using 1999 State Quarter dies since dollar-sized blanks weren’t yet available. Approximately 15-20 pieces across all five 1999 states were struck on these test planchets.

These quarters exhibit golden coloring or greenish hue, weigh 5.9-6.3 grams versus standard 5.67 grams, and show thicker profiles with irregular edges.

Spectroscopic analysis revealed composition of copper, zinc, manganese, and nickel. Four composition types exist with or without copper cores. The Treasury acknowledged conducting metallurgical tests but declined detailed information.

Authenticated examples have sold between $3,000 and $15,000 at major auctions depending on state and composition type.

FAQ About 1999 Quarter

1. How can I tell if my 1999 quarter is valuable?

Check the mint mark below “IN GOD WE TRUST” (P for Philadelphia, D for Denver, S for San Francisco). Examine the coin’s surface for wear and luster quality.

Silver proof versions from San Francisco weigh more (6.25 grams vs. 5.67 grams) than standard quarters. Look for minting errors like the Delaware “Spitting Horse” die crack or off-center strikes.

Professional grading services like PCGS or NGC can authenticate and grade valuable specimens.

2. What is the 1999 Delaware “Spitting Horse” quarter error?

The “Spitting Horse” is a die crack error found only on 1999-P Delaware quarters. A raised line extends from the horse’s mouth down through the letter “C” in “Caesar.”

This error occurred when the striking die developed a crack during production, causing metal to fill the void and create a distinct raised line.

Circulated examples with clear die cracks sell for $3-$20, while uncirculated specimens can reach $40 or more. Professional grading can push values above $50 for well-preserved examples.

3. Why do some 1999 quarters sell for thousands of dollars?

Exceptional grades drive high prices. Only 5 coins were certified PCGS MS68 for 1999-P Georgia, with none higher. Rarity at premium grades creates significant collector demand.

First-year status of the 50 State Quarters Program adds appeal. The 1999-P Pennsylvania MS67 sold for $10,200, demonstrating how condition rarity exceeds mintage numbers in importance.

Silver proof coins in perfect PR70 grade combine 90% silver content with flawless surfaces, creating premium valuations. Error varieties and experimental planchet strikes also command substantial prices.
