Collectible coins often encompass a wide range of types, including currency issued by the United States of America (USA) and various commemorative pieces such as U.S. Mint medals. The U.S. Mint produces medals for various purposes, including honoring individuals, events, and significant achievements in American history. The Julian reference typically refers to the Julian catalog, a classification system used for U.S. Mint medals, which helps collectors identify and evaluate these items based on factors like rarity, historical significance, and condition. Medals from around 1940 may commemorate significant events from that era, making them particularly desirable among collectors.
