So-Called Dollars refer to a category of commemorative coins and medals that were issued to commemorate events, people, or places, primarily during the late 19th and early 20th centuries. The term is derived from the fact that these items were not intended to be legal tender but were often used in a similar context. The Hibler-Kappen catalog is a well-known reference for collectors of these items, listing various pieces along with their historical significance and market values. The 1875 So-Called Dollar features imagery related to the Centennial Exposition, celebrating the 100th anniversary of the signing of the Declaration of Independence, and is a popular item among collectors of U.S. numismatic history.
