Collecting coins can be a rewarding hobby, especially when certain pieces in your collection are worth significantly more than their face value. While many quarters minted after 1965 are common, some rare specimens can fetch over $10,000 due to unique errors, low mintage, or exceptional condition. Here are the top seven quarters minted after 1965 that could be worth a small fortune:
1. 1965 Silver Washington Quarter Error
In 1965, the U.S. Mint transitioned from silver to a copper-nickel clad composition for quarters. However, a few 1965 quarters were mistakenly struck on leftover 90% silver planchets from 1964. These error coins are extremely rare and highly sought after by collectors.
- Composition: 90% silver (error)
- Estimated Value: Up to $14,687.50, depending on condition
- Notable Sale: One sold for $14,687.50 in AU58 condition
2. 1966 Washington Quarter (MS68+ Grade)
While billions of 1966 quarters were produced, finding one in near-perfect condition is exceptionally rare. Quarters graded MS68+ (Mint State) are among the finest known examples and command high prices at auctions.
- Grade: MS68+
- Estimated Value: Up to $21,000
- Notable Sale: One sold for $21,000
3. 1970-S Proof Washington Quarter (Struck on 1941 Canadian Quarter)
A fascinating mint error occurred in 1970 when a U.S. quarter was mistakenly struck on a 1941 Canadian quarter planchet. This error resulted in a thinner coin with unique markings, making it highly valuable.
- Error Type: Struck on 1941 Canadian quarter
- Estimated Value: Over $35,000
- Notable Sale: One sold for over $35,000
4. 1983-P Washington Quarter (Double Die Reverse)
Some 1983-P quarters exhibit a double die error on the reverse side, where the design elements appear doubled. These errors are rare and can significantly increase the coin’s value.
- Error Type: Double die reverse
- Estimated Value: Up to $15,000
- Notable Sale: One sold for $15,000
5. 1982-P Washington Quarter (MS68 Grade)
Due to the lack of mint sets in 1982, high-grade 1982-P quarters are scarce. Coins graded MS68 are particularly valuable.
- Grade: MS68
- Estimated Value: Up to $10,200
- Notable Sale: One sold for $10,200
6. 1976-S Silver Bicentennial Quarter (MS69 Grade)
The 1976-S Bicentennial Quarter struck in 40% silver, is notable. Coins graded MS69 are among the highest quality known.
- Grade: MS69
- Estimated Value: Up to $19,200
- Notable Sale: One sold for $19,200
7. 1967 Special Mint Set (SMS) Washington Quarter
In 1967, the U.S. Mint issued Special Mint Sets instead of regular proof sets. Quarters from these sets, especially those in pristine condition, are highly prized.
- Type: Special Mint Set
- Estimated Value: Up to $17,000
- Notable Sale: One sold for $17,000
