Roosevelt dime

Silver Roosevelt dimes, 1946 to 1964 Any Roosevelt dime dated 1964 or earlier is 90% silver; from 1965 the Mint switched to the copper-nickel sandwich still used today. The quickest way to spot one in a stack is the edge: a clad dime shows a copper stripe, a silver one is bright all the way around. Silver dimes are uncommon in change because people pull them out, but they remain legal tender and still slip through, and each is worth well over ten cents for its metal alone.
