Collectible coins encompass a wide range of items, including currency, commemorative coins, and medals. In the United States, collectible coins often celebrate historical events or figures, while modern medals issued in recent years, such as 2015, may feature contemporary designs. "Unknown" refers to pieces lacking specific identification or provenance, which can affect their desirability and market value. Collectors focus on factors like rarity, condition, and historical significance when assessing the worth of these coins and medals.
