Collectible coins encompass a wide range of items, including currency types like the United States One Dollar coin and tokens, which are often used for specific purposes such as transportation or promotional activities. The U.S. One Dollar coin has seen various designs and materials over the years, reflecting different periods in American history. Miscellaneous medallic tokens and fantasy coinage, particularly from the 1960s, often serve as artistic representations or commemorative pieces rather than legal tender, appealing to collectors interested in unique designs and thematic significance.
