The US half dollar minted since 1964 has John Kennedy's portrait. Those minted in 1964 are 90% pure silver. Those from 1965 to 1970 are 40% silver. All minted after 1970 (except those included in silver proof sets) are copper-nickel and contain no silver.

US Mint "Prestige" proof sets include 90% silver Kennedy Halves, although all others versions of the coin including standard proofs are made of copper-nickel.
