United States quarters minted in 1967 do not contain any silver. The composition of these coins is primarily copper-nickel clad, consisting of a copper core with outer layers of nickel and copper. This change in composition occurred following the Coinage Act of 1965, which removed silver from circulating dimes and quarters.
The shift away from silver coinage was prompted by rising silver prices, which made the intrinsic value of silver coins exceed their face value. Consequently, individuals began hoarding silver coins, leading to shortages in circulation. The transition to base metal coinage was intended to stabilize the money supply and prevent further disruption to the economy.
