So-Called Dollars are a type of exonumic coinage that were issued to commemorate specific events, organizations, or individuals and generally do not have legal tender status. The term was popularized by the Hibler and Kappen reference book, which catalogs these types of pieces. Many So-Called Dollars were produced in the United States, and a notable example is from 1888, which commemorates the Civic and Industrial Exposition in Nashville, Tennessee. These coins are collected for their historical significance and artistic designs, often representing cultural or regional themes.
