Half Dollars represent some of America's most beautiful coinage, including the Flowing Hair, Draped Bust, Capped Bust, Seated Liberty, Barber, Walking Liberty, Franklin, and Kennedy designs. The Walking Liberty Half Dollar (1916-1947) is considered one of the most artistic U.S. coins. Kennedy Half Dollars, first minted in 1964 following President Kennedy's assassination, were widely hoarded and remain popular. Silver content ended in 1971, though special collector versions are still produced.
