Collectible coins, particularly in the United States, encompass various types that attract numismatists and enthusiasts. The 50-cent denomination, specifically the Kennedy Half Dollar, was first issued in 1964 to honor President John F. Kennedy following his assassination. These coins feature the profile of Kennedy on the obverse and the Presidential Seal on the reverse. The San Francisco Mint produced proofs and special editions, particularly during the Bicentennial year of 1776, which included unique designs celebrating American history. Collectors often seek these coins in different grades, with considerations for mint marks and condition significantly impacting value.
