Collectible coins known as "So-Called Dollars" refer to a category of medals and coins that commemorate events, individuals, or places, often issued in connection with various centennial or historical celebrations. The term is predominantly associated with the United States, particularly during the late 19th and early 20th centuries. The "1922 One Dollar" variety refers specifically to a commemorative piece, celebrating a significant event or milestone within that period. These items appeal to collectors due to their historical significance, artistic design, and limited production, often increasing in value over time as demand rises.
