How much silver used in making dollars after 1965?

However, in 1965, the Coinage Act of 1964 removed silver from all circulating US coins except for the half dollar. The half dollar was changed from 90% silver to 40% silver in 1965, and then to a composition of 75% copper and 25% nickel in 1971. Today, all US coins are made from copper-plated zinc or copper-plated nickel, and do not contain any silver.
