Do pre 1964 nickles have silver?

Yes, pre-1964 nickels, specifically the ones minted from 1942 to 1945, contain silver. During World War II, the U.S. Mint produced these "War Nickels" with a composition of 56% copper, 35% silver, and 9% manganese to conserve nickel for the war effort. However, nickels minted before 1942 and after 1945 do not contain silver and are made of a copper-nickel alloy.
