Collectible coins encompass a variety of types, including numismatic coins, which are valued for their historical significance, rarity, and condition. Medals are often created for commemorative purposes or as awards, distinct from traditional currency. The United States of America issues various collectible sets, such as Modern Commemorative Sets, which feature coins produced to honor significant events, individuals, or anniversaries. In 2018, collectors could obtain coins from both the Philadelphia and Denver mints, showcasing different designs and features specific to that year.
