Collectible coins encompass a variety of types, including circulation coins, commemorative coins, and private tokens, which are often sought after by numismatists. In the United States, the U.S. Mint produces medals that often feature historical figures, events, or themes. The Julian catalog references a system for identifying American medals, including those minted in 1918, which may commemorate significant milestones such as World War I. Collectors often evaluate coins based on rarity, condition, and historical significance, influencing their market value.
