Collectible coins encompass various types of numismatic items, including currency, medals, and tokens. In the United States, collectible coins can include commemorative pieces such as the five-dollar coins issued for special occasions or events. Disney-themed medals from 1987, for example, are sought after by collectors due to their nostalgic value and limited mintage. Each collectible coin or medal possesses unique characteristics, such as design features and historical significance, that contribute to its desirability and value in the collector community.
