So-Called Dollars are a type of commemorative medallion or token that originated in the United States during the late 19th and early 20th centuries, with the term commonly applied to pieces struck for various events, fairs, and expositions. The 1926 So-Called Dollar is associated with the centenary of the Missouri state and was produced in a variety of metals, often sought after by numismatists.
