So-Called Dollars are a category of medals and tokens that were produced primarily in the United States from the mid-19th century onward, often commemorating significant events or individuals. The term "So-Called Dollar" originates from the book "So-Called Dollars" by Harold Mason, published in 1964, which cataloged these items. Among these, the 1861 So-Called Dollar is notable for commemorating the Civil War and features varying designs related to the events of that year. These collectibles are sought after by numismatists for their historical significance, artistic designs, and representation of American culture during the 19th century.
