Collectible coins encompass a wide variety of types, including historical coins, commemoratives, and bullion. The United States Mint produces a range of collectible items, including U.S. Mint Medals, which honor notable events, individuals, or themes. The Julian cataloging system, established by numismatist David Julian, provides reference numbers for various U.S. Mint Medals and other related items, such as those minted in 1826, which may be sought after by collectors for their historical significance and artistic design.
