If you have a habit of tossing spare change into a jar, it might be time to take a closer look. Some quarters minted over two decades ago have become highly sought-after collectibles, fetching impressive sums in the numismatic market. Here are five such quarters that could turn your pocket change into a small fortune.
1. 2004-D Wisconsin State Quarter – Extra Leaf Error

In 2004, the U.S. Mint released the Wisconsin state quarter featuring a cow, a wheel of cheese, and an ear of corn. However, some of these coins were minted with an additional leaf on the corn stalk-either a “High Leaf” or “Low Leaf” variation. These anomalies are believed to be minting errors, and their rarity has made them valuable among collectors.
- Estimated Value: Circulated versions can fetch between $50 and $130, while uncirculated specimens have been known to sell for up to $1,500.
2. 2005-P Minnesota State Quarter – Doubled Die Error

The Minnesota state quarter, released in 2005, depicts a lake scene with a canoeist and a dense forest. Some of these coins exhibit a doubled die error, where elements of the design, particularly the trees, appear duplicated due to a misalignment during the minting process.
- Estimated Value: Depending on the severity of the doubling and the coin’s condition, values range from $50 to over $300.
3. 1999-P Delaware State Quarter – “Spitting Horse” Error

As the first coin in the 50 State Quarters series, the Delaware quarter holds a special place in U.S. coinage. A particular error, known as the “Spitting Horse,” features a die crack that gives the appearance of the horse on the coin’s reverse “spitting.”
- Estimated Value: While minor die cracks are common, this specific error has garnered attention, with values ranging from $10 to $20 for circulated coins.
4. 1965 Washington Quarter – Silver Composition Error

In 1965, the U.S. Mint transitioned from 90% silver quarters to a copper-nickel clad composition. However, a few quarters from that year were mistakenly struck on silver planchets intended for earlier coins.
- Estimated Value: These rare silver 1965 quarters can be worth between $4,000 and $7,000, depending on their condition.
5. 1982-P Washington Quarter – No Mintmark

Typically, quarters minted in Philadelphia bear a “P” mintmark. However, due to a change in the minting process in 1982, some quarters were produced without this identifying mark, making them rare finds.
- Estimated Value: Depending on condition, these no-mintmark quarters can be valued between $100 and $2,500.
Tips for Identifying Valuable Quarters
- Examine the Details: Use a magnifying glass to inspect your quarters for any anomalies, such as extra design elements or doubling.
- Check the Edges: Silver quarters have a distinct appearance compared to their copper-nickel counterparts. Look for a solid silver edge without the copper stripe.
- Weigh Your Coins: Silver quarters weigh approximately 6.25 grams, whereas clad quarters weigh about 5.67 grams. A precise scale can help identify potential silver errors.
- Consult Reputable Sources: For more information on coin values and authentication, visit the U.S. Mint and the Professional Coin Grading Service (PCGS).
Conclusion
While most quarters are worth their face value, certain errors and rare mintages have turned everyday coins into valuable collectibles. By paying attention to specific details and anomalies, you might discover that some of your spare change is worth significantly more than 25 cents.
