So-Called Dollars are a category of commemorative medals and tokens that resemble dollar coins but were not issued as official currency by the United States. They were typically produced to commemorate specific events, expositions, or individuals. The term "So-Called Dollar" originated from the 1933 reference book by Harold S. Souders, which cataloged these items. The 1882 So-Called Dollar, associated with the 1882 New Orleans Exposition, is one of the more recognized examples within this form of collectible, reflecting a blend of numismatic and historical significance.
