Collectible coins are often sought after by numismatists for their historical significance, rarity, and aesthetic value. In the United States, one notable collectible is the Kennedy Half Dollar, which was first minted in 1964 to honor President John F. Kennedy. The 50-cent coins, including those from the year 2020, may vary in value based on their condition, mint marks, and whether they are part of limited editions or special releases. Collectors often assess these factors to determine the desirability and market value of specific coins within this category.
