Among these treasures, error quarters hold a special place due to their widespread use and the potential for high value.

While most quarters jingling in your pocket are worth only their face value or metal content, some error quarters are still circulating—and they could be worth hundreds or even thousands of dollars. In this article, we’ll explore the 9 most expensive error quarters that might still be hiding in circulation, waiting to be discovered.

1. 1970-S Proof Washington Quarter

The 1970-S Proof Washington Quarter is famous for a rare minting error where the “S” mint mark is missing. This mistake occurred during the proof coin production process at the San Francisco Mint, creating an incredibly scarce variety.

An example graded PR-69 sold for $28,000 in 2023. Its rarity and unique flaw make it one of the most valuable error quarters still out there.

2. 1965 Silver Quarter

In 1965, the U.S. Mint transitioned from 90% silver quarters to copper-nickel clad compositions. However, a small number of 1965 quarters were accidentally struck on leftover silver planchets, making them highly sought after by collectors.

A gem-quality example graded MS-65 sold for $25,000 in 2022. Its unexpected composition and limited availability ensure its desirability.

3. 1943 Doubled Die Obverse Washington Quarter

The 1943 Doubled Die Obverse Washington Quarter features dramatic doubling on the obverse side, particularly visible in the word “LIBERTY” and the date. This striking error adds significant value to an already desirable coin.

An exceptionally well-preserved specimen sold for $22,000 in 2023. Its rarity and eye-catching flaw make it a standout piece in any collection.

4. 1999-P Georgia State Quarter

The 1999-P Georgia State Quarter made headlines when a mule error was discovered. A mule occurs when the obverse and reverse designs come from different coin series—in this case, pairing the State Quarter obverse with a non-matching reverse.

This extraordinary error coin sold for $20,000 in 2021. Its uniqueness and cross-series design make it a must-have for serious collectors.

5. 2000-W Sacagawea Dollar/Quarter Mule

One of the most famous mule errors in U.S. numismatics, the 2000-W Sacagawea Dollar/Quarter Mule combines the obverse of a Sacagawea Dollar with the reverse of a Washington Quarter. Only a handful of these coins exist, making them exceedingly rare.

An example of this hybrid coin sold for $18,000 in 2023. Its extreme rarity and historical intrigue ensure its status as a prized find.

6. 1976 Bicentennial Quarter

The 1976 Bicentennial Quarter, featuring a colonial drummer boy design, was accidentally struck on a nickel planchet during production. This error resulted in a smaller, thinner quarter with a distinct appearance.

An example graded MS-65 sold for $15,000 in 2022. Its unusual size and rarity make it a standout piece.

7. 1982 No “P” Mint Mark Roosevelt Dime

While technically a dime error, some collectors mistakenly identify the 1982 No “P” Mint Mark Roosevelt Dime as a quarter due to its similar size. This confusion has led to its inclusion in quarter-focused searches, but it remains a valuable error coin.

An example graded MS-67 sold for $14,000 in 2023. Its intriguing flaw and scarcity make it a favorite among error coin enthusiasts.

8. 2009-D District of Columbia Quarter

The 2009-D District of Columbia Quarter is notable for a double-struck off-center error, where the coin was struck twice and misaligned during the minting process. This dramatic flaw creates a visually striking and highly collectible piece.

An example of this error sold for $12,000 in 2021. Its quirky appearance and rarity contribute to its appeal.

An example graded MS-66 sold for $10,000 in 2023. Its unique flaw and limited availability ensure its desirability.

Why Are These Error Quarters Still in Circulation?

Despite their age and value, many error quarters remain in circulation because:

1. Durability: Made primarily of copper-nickel, these coins are highly durable and resistant to wear.
2. Lack of Awareness: Many people don’t realize the potential value of older or flawed coins, allowing them to remain in everyday use.
3. Hoarding and Resurfacing: Coins hoarded for decades often resurface through estate sales, bank rolls, or coin exchanges.

What Makes These Error Quarters So Valuable?

Several factors contribute to the staggering prices these error quarters command:

1. Rarity: Errors such as doubled dies, missing mint marks, or wrong planchet strikes occur infrequently, making these coins exceptionally scarce.
2. Condition: Coins in pristine, high-grade condition are exponentially more valuable than worn or damaged specimens.
3. Historical Significance: Many of these errors commemorate important events or milestones, adding intrinsic value and patriotic significance.
4. Visual Uniqueness: Minting errors create eye-catching designs that captivate collectors and enhance their desirability.

Could You Have a Fortune in Your Pocket?

While stumbling upon one of these rare error quarters in everyday circulation is unlikely, it’s not impossible. Savvy collectors often search through rolls of coins, estate sales, and online marketplaces for hidden gems. If you come across a quarter with unusual markings, a misaligned design, or other oddities, consider having it appraised by a professional—it might just be worth a fortune!
