So-Called Dollars are a type of medal or token that were issued primarily by private organizations to commemorate specific events or themes, often resembling the size and shape of a dollar coin. The term originated from the 19th century, and while they are not official currency, they are collected for their historical and artistic significance. The 1961 So-Called Dollar refers to a specific piece connected to the centennial of the American civil war, often depicting themes or figures relevant to that period. Collectors often focus on the design, rarity, and the historical context surrounding each piece.
