Collectible coins include various types such as commemorative coins, bullion coins, and historical pieces that are often sought after by numismatists. The United States Mint produces a range of collectible coins, including special editions and medals celebrating significant events or figures. For example, the Julian cataloging system helps identify U.S. Mint Medals, with some dated as far back as 1867. Coins classified as "Unknown" may lack specific details regarding their origin or historical context but can still hold significance for collectors.
