1971–Present Kennedy Half Dollars | Copper-Nickel Clad & Modern Collector Issues
The Kennedy half dollar, first issued in 1964 to commemorate the fallen President John F. Kennedy, underwent a significant compositional change in 1971. After clinging to a 40% silver alloy from 1965 through 1970, the series fully transitioned to a copper-nickel clad composition starting in 1971—mirroring the circulating dimes and quarters of the time.
Composition and Circulation
Beginning in 1971, the Kennedy half dollar was struck on a planchet composed of:

2014: A special 50th Anniversary Kennedy Half Dollar was struck in .9999 fine gold, dual-dated 1964–2014, and minted at West Point—a landmark release for modern U.S. coinage.
Circulation Decline and Modern Availability
Despite the switch to base metal, the Kennedy half dollar continued to be minted in large numbers through the 1970s and early 1980s. However, public confusion over its supposed intrinsic value—due to lingering associations with silver—led to widespread hoarding. The denomination gradually disappeared from circulation.
By 2002, the U.S. Mint halted regular production for circulation. Since then, Kennedy half dollars have been struck exclusively for collectors, available in:
