Collectible coins are numismatic items that are sought after for their historical significance, rarity, or aesthetic value. In the United States, a notable example is the Kennedy Half Dollar, which was first issued in 1964 to commemorate President John F. Kennedy following his assassination. The 50-cent coin, known for its depiction of Kennedy, has seen various designs and mintages over the years, including special editions like the 2023 release. Collectors often focus on factors such as mint marks, grades, and historical context when assessing the value of these coins.
