Collectible coins encompass a range of numismatic items, including historical coins, commemorative pieces, and medals issued by mints. In the United States, collectible coins often feature significant national symbols or events and are produced by the U.S. Mint. The Julian reference pertains to a system for categorizing coins and medals, and the year 1913 is notable for certain rare coins, such as the 1913 Liberty Head nickel, which holds a legendary status among collectors due to its limited mintage and striking design. U.S. Mint medals, which are not currency but are produced for various commemorative and ceremonial purposes, also form an important subset of collectible items.
