So-Called Dollars are a type of commemorative silver medal or token, primarily issued in the United States, that commemorate an event, person, or place and resemble the size and appearance of a dollar coin. Originating in the mid-19th century, with significant examples emerging in 1859, these pieces often feature elaborate designs and are collectible due to their unique historical significance. The term "So-Called Dollar" was popularized by the numismatic author Harold S. Betts in the 1930s, and these items are cataloged in "So-Called Dollars: A Comprehensive Catalog" by L. M. D. Bowers and others. They are highly valued by collectors for their artistry and the historical context they represent.
