Kennedy Half Dollar (1964–present)

Rushed into production within months of the Kennedy assassination, replacing the Franklin half. The 1964 issues were 90% silver; 1965–1970 dropped to 40% silver clad; 1971 onward is copper-nickel clad. Heavy hoarding kept the series largely out of circulation. The 1976 Bicentennial reverse (Independence Hall) was struck dual-dated 1776–1976.
