The Kennedy Half Dollar, first minted in 1964, commemorates President John F. Kennedy and is produced in both circulation and proof versions. The 2004 San Francisco mint, known as the S mint mark, produced proof coins that are highly sought after by collectors due to their high-quality finish. These coins typically feature a deep cameo contrast between the frosted foreground and the mirrored background, enhancing their aesthetic appeal. Collectors often seek out specific dates and mint marks, with the 2004 San Francisco variant being a popular choice for numismatists.
