So-Called Dollars are a type of collectible medallion or token that are associated with the United States, typically produced for commemorative purposes. They emerged in the late 19th century and often feature designs related to significant events, organizations, or individuals. The term "So-Called Dollar" originates from a 1936 book by Harold T. Smith, which cataloged these items. Specifically, the 1880 So-Called Dollar (SC 1) commemorates the opening of the New York City branch of the U.S. Mint, appealing to numismatists and collectors for its historical significance and unique imagery.
