Collectible coins encompass a wide range of numismatic items, including historical, commemorative, and currency types. In the United States, collectible coins can include issues from the U.S. Mint as well as tokens representing specific states or events. Hawaii tokens, such as those cataloged by Medcalf, often reflect the unique history and culture of the Hawaiian Islands. The year 1964 is notable for various coin issues, including the last year of silver coins in circulation in the U.S. Additionally, "unknown" might refer to coins or tokens with uncertain origins or limited documentation, adding an element of mystery to the collecting experience.
