Although quarters were never made entirely of silver, the U.S. Mint completely stopped using silver in quarters in 1965, producing the last actual silver quarters in 1964. Prior to 1965, the Mint made quarters out of 10 percent copper and 90 percent silver.
U.S. dimes, quarters, and half-dollars dated prior to 1965 were minted of 90% silver/10% copper. Large quantities in circulated condition are readily available. Common-date uncirculated coins are available but carry premiums over circulated coins.
