Collectible coins encompass a wide range of items, including historical coins, commemorative pieces, and bullion coins, which are sought after for their aesthetic, historical, or intrinsic value. The U.S. Mint, established in 1792, produces various coin and medal types, including the U.S. Mint Medals, which honor significant achievements or individuals throughout American history. The Julian catalog system is used by numismatists to classify and identify medals and tokens, with the 1821 issue representing one of many significant years in the numismatic timeline. Collectors often face challenges in determining the provenance and authenticity of these coins and medals, particularly those with limited or unknown mintage histories.
