Currently, silver coins are sold only to collectors and investors. Silver coins have not been made for circulation since the 1960s. The mint at San Francisco makes proof versions of normal copper-nickel circulation coins, and the mint at West Point makes bullion pieces.
Circulation coins are made at Philadelphia and Denver. Very occasionally West Point also mints cents when demand is high.
