Why These Quarters Are Valuable
Silver Content
All quarters from 1956–1964 contain 90% silver, making them valuable for their bullion content. A full roll of 40 coins contains about 7.23 troy ounces of silver, which translates to over $200–$250 in melt value, depending on current silver prices.
Key Dates and Mint Marks
Some years and mint marks are particularly sought after by collectors. The table below highlights notable years and mint marks from 1956–1964 and factors that can increase their value:
| Year | Mint Mark | Notable Value Factors |

| 1964 & 1964-D | P/D | Last year of 90% silver; special varieties exist |
Error Coins and Varieties
Collectors are especially interested in quarters with errors and special varieties. Examples include:
- Doubled Die Obverse (DDO): Notable in 1957-D and 1960-D
- Doubled Die Reverse (DDR): Found in 1964-D
- Repunched Mint Marks (RPM): Occurs in 1956-D and 1963-D
- Off-Center Strikes: Any year
- Clipped Planchet: Any year
- Proof Strikes: Mirror-like finish from San Francisco Mint (1956–1964)
High-grade coins, particularly MS66–MS68 for circulation coins and PR68–PR70 for proofs, can fetch thousands of dollars at auction.
Condition and Eye Appeal
The condition of a coin greatly affects its value. Coins with strong toning or exceptional eye appeal can command premiums even beyond their grade. Cleaning or polishing can significantly reduce collector value.
