9 Rare Quarter Error Coins Worth Serious Money

9 Rare Quarter Error Coins Worth Serious Money: Quarters are often dismissed as loose change, jingling around in pockets or piling up in jars. But what if some of those seemingly ordinary coins could be worth a small fortune? While most quarters hold only their face value, certain error coins have slipped through the cracks, waiting to be discovered by sharp-eyed collectors.

Minting errors, such as misaligned designs, missing elements, or unusual materials, can turn an otherwise common coin into a rare and valuable treasure. In this article, we’ll explore the 9 most valuable quarter error coins that could make you rich.

1. 2004-D Wisconsin State Quarter

The 2004 Wisconsin State Quarter is one of the most famous error coins in modern numismatics. This quarter features an “extra leaf” on the ear of corn depicted on the reverse side. There are two variations: the “High Leaf” and “Low Leaf,” both of which are incredibly rare.

An example of the High Leaf variety graded MS-67 sold for $8,000 in 2023. Its quirky flaw and scarcity make it one of the most sought-after error quarters.

2. 2005 Minnesota State Quarter

The 2005 Minnesota State Quarter features another fascinating minting error—an extra tree appears on the reverse design. This anomaly occurred during production, creating a rare and highly desirable variation.

A high-grade example of this error coin sold for $6,500 in 2022. Its distinctive appearance and rarity ensure its status as a collector’s dream.

3. 2000-P Sacagawea Dollar/Quarter Mule

In 2000, a remarkable mule error was discovered when a Sacagawea Dollar obverse was paired with a Washington Quarter reverse. This hybrid coin is extraordinarily rare, given the strict quality control measures at the U.S. Mint.

An example of this mule error sold for $5,000 in 2021. Its cross-series design and historical intrigue make it a must-have for serious collectors.

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 $4,200 in 2022. Its uniqueness and cross-series design make it a must-have for serious collectors.

5. 2009 District of Columbia Quarter

The 2009 District of Columbia Quarter occasionally features a fascinating error where it is struck on a dime-sized planchet instead of the standard quarter-sized blank. This results in a smaller-than-normal coin with incomplete designs.

An example of this error sold for $4,500 in 2023. Its unusual size and rarity make it a prized addition to any collection.

6. 1970-D Washington Quarter

No Washington Quarters were issued for circulation in 1970; instead, they were only available as part of mint sets or proof sets. The 1970-D Washington Quarter, struck at the Denver Mint, is particularly sought after due to its limited availability.

A high-grade proof example graded PR-69 sold for $4,200 in 2023. Its exclusivity and pristine condition make it a prized addition to any collection.

7. 1965 Silver Quarter

Most Washington Quarters minted after 1964 contain copper-nickel rather than silver. However, a small number of 1965 quarters were accidentally struck on leftover silver planchets, creating a highly sought-after error coin.

One such example sold for $4,500 in 2020. Its unexpected composition and limited availability make it a modern rarity with substantial value.

An exceptionally well-preserved specimen sold for $4,000 in 2021. Its rarity and eye-catching error make it a standout piece in any collection.

9. 1976 Bicentennial Quarter

The 1976 Bicentennial Quarter occasionally features a double die obverse error, where the inscriptions and design elements appear slightly doubled. This striking flaw adds significant value to an otherwise common coin.

A high-grade example graded MS-66 sold for $3,200 in 2022. Its visual appeal and rarity make it a favorite among error coin enthusiasts.

What Makes These Quarter Error Coins So Valuable?

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