1. 1970-S Proof Washington Quarter
The 1970-S Proof Washington Quarter is one of the most famous error quarters to date. It’s supposed to feature the “S” mint mark denoting the San Francisco Mint. However, a rare batch of these proof coins lacks this mark entirely, making them incredibly valuable. A near-perfect coin from this group fetched an impressive $28,000 at auction. If you’re lucky enough to stumble across one, you could be holding one of the most valuable expensive error quarters out there.
2. 1965 Silver Quarter
The U.S. Mint officially stopped using silver for quarters in 1965, transitioning to copper-nickel clad coins. Yet, a few 1965 quarters were mistakenly struck using leftover silver blanks. These coins blend in with regular quarters, but their silver content makes them stand out to knowledgeable collectors. An MS-65 graded example was sold for around $25,000, making it a truly rare discovery for anyone checking their spare change.
3. 1943 Doubled Die Obverse Washington Quarter
The 1943 Doubled Die Obverse Washington Quarter has an eye-catching error: the design on the front of the coin appears doubled, especially around the word “LIBERTY” and the date. This doubling occurred during the minting process and is highly noticeable to collectors. One pristine version of this coin sold for $22,000. It’s not only historically significant but also a standout among expensive error quarters.
4. 1999-P Georgia State Quarter
Most state quarters are common, but the 1999-P Georgia State Quarter has an error that makes it incredibly rare: a mule mistake. This happens when two mismatched coin dies are used, resulting in the Georgia quarter being paired with a reverse design from a completely different series. Only a few of these exist, and one was sold for $20,000. Its uniqueness has solidified its status as a must-have for serious collectors.
5. 2000-W Sacagawea Dollar/Quarter Mule
One of the most intriguing and talked-about mint errors is the 2000-W Sacagawea Dollar/Quarter Mule. Instead of having the correct designs, these coins feature the front of a Sacagawea Dollar and the back of a Washington Quarter. Only a limited number have been found, making them extremely rare. Collectors have paid up to $18,000 for one of these hybrid coins. It’s truly one of the strangest and most valuable expensive error quarters you could find.
6. 1976 Bicentennial Quarter
The 1976 Bicentennial Quarter with its colonial drummer boy design is well-known, but certain versions have an error that sets them apart. Some were mistakenly struck on nickel planchets, resulting in a quarter that is thinner and lighter than usual. An example graded MS-65 sold for $15,000. If you come across an unusually small or light Bicentennial Quarter, it might be one of these rare error coins.
7. 1982 No “P” Mint Mark Roosevelt Dime
Though technically a dime, the 1982 No “P” Mint Mark Roosevelt Dime often gets confused with quarters due to its size and the fact that it’s missing the “P” mint mark. This error was overlooked by many when it was first released. A well-preserved example has fetched $14,000, making it an appealing find for anyone searching for expensive error quarters.
8. 2009-D District of Columbia Quarter
The 2009-D District of Columbia Quarter is known for an eye-popping double-struck off-center error. Essentially, the coin was struck twice but misaligned, giving it a distorted and striking appearance. This kind of visible error is rare, which is why one of these coins sold for $12,000. It’s an ideal find for collectors hunting unique flaws.
9. 2005-P Kansas State Quarter
The 2005-P Kansas State Quarter carries a prominent die crack error. This crack visibly cuts across the design, making the coin easily identifiable. Because of its distinct appearance and limited numbers, collectors are willing to pay up to $10,000 for high-grade examples of this particular quarter.
