Collectible coins encompass various types, including official currency issued by governments and tokens, which are private or commercial items used as substitutes for currency. In the United States, the iconic "One Dollar" coin has had several versions, including the Eisenhower, Susan B. Anthony, and Sacagawea dollars. Hard Times Tokens were struck during the economic distress of the 1830s and often depict political messages or advertisements. The Rulau catalog specializes in detailing these tokens and their historical significance, providing collectors with comprehensive insights into numismatic items.
