Collectible coins often encompass a variety of types, including historical coins, commemorative issues, and medals produced by mints. The United States Mint, for example, has issued numerous medals, such as those featuring designs by renowned engraver Frank Gasparro, including notable pieces from 1958. Collectors often seek out items based on factors like rarity, condition, historical significance, and artistic appeal, with variations like the Julian catalog references aiding in the identification and valuation of these pieces. U.S. Mint medals, separate from currency, commemorate events, individuals, or themes and are prized for their craftsmanship and historical context.
