So-Called Dollars are commemorative medals that were created to honor specific events, individuals, or places and typically resemble U.S. dollar coins in size and style. They emerged in the United States around the mid-19th century, with the first significant issuance occurring around 1860. The term "So-Called Dollar" was first used by numismatist Harold M. S. Smith in his 1963 catalog of these items. Some of the notable examples include pieces minted in relation to expositions, fairs, and anniversaries, with a variety of designs that reflect their commemorative nature. The reference "SC 1" denotes the first piece in Smith's reference catalog, indicating its historical significance within this category of collectibles.
