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.
From 1837 through 1964 the silver percentage was 90%. From 1965 through 1970 half dollars and silver (Eisenhower) dollars were made with a core of 21% silver, clad with an outer layer made from 80% silver. From 1971 through the present the US Mint has produced no coins for circulation that contain any silver.
