The Legacy of the Kennedy Half Dollar (1964–1978)

The Kennedy Half Dollar was one of the first key monuments made to the president after his assasination. The public embraced it instantly, and the coin became extremely popular during the whole series.

Originally struck in 90% silver, the series transitioned to 40% silver (1965–1970) and to a copper-nickel clad composition by 1971. Despite being intended for circulation, most Kennedy Half Dollars by the late 1970s were hoarded or saved. It resulted in many surviving examples in uncirculated condition today.

Transition from Silver to Copper-Nickel

Economic pressures of the late 1960s made silver coinage unsustainable for circulation. By 1978, the half dollar contained no silver at all, but retained Kennedy’s portrait and the familiar patriotic motif.
