Collectible coins can be categorized into several types, including numismatic coins, bullion coins, and proof coins. Medals, distinct from coins, are often commemorative and produced by mints, such as the U.S. Mint, which issues a variety of medals recognizing historical events, notable figures, and national achievements. In 2020, the U.S. Mint released several medals, reflecting diverse themes and honoring significant contributions to American history and culture. Collectors often seek these items based on rarity, historical significance, and artistic design.
