Collectible coins refer to numismatic items that are valued for their rarity, historical significance, and condition rather than their face value. In the United States, collectible coins include various denominations, such as the fifty-cent coins, commonly known as half dollars. One notable type is the Kennedy Half Dollar, which was first issued in 1964 to commemorate President John F. Kennedy's legacy following his assassination. Coins minted in 1990 as part of the Kennedy series are part of a broader collection sought after by enthusiasts and investors alike.
