Collectible coins encompass a wide range of numismatic items, including historical currency, commemorative pieces, and medals. Notably, U.S. Mint medals, such as those produced for various events or notable figures, have gained popularity among collectors. One example includes the Julian reference system, which catalogs U.S. Mint medals, with some pieces dating back to significant years like 1855, reflecting important moments in American history and culture. Collectors often focus on the rarity, condition, and historical significance of these items to determine their value.
