So-Called Dollars are a type of commemorative medal or token issued primarily in the United States, often celebrating events, people, or places significant to American history. The term is derived from a series of medals that were produced in the late 19th and early 20th centuries, particularly around the time of the 1893 World's Columbian Exposition in Chicago. The 1897 So-Called Dollar, specifically, refers to a medal struck to commemorate the trans-Mississippi and international exposition held in Omaha, Nebraska, between 1898 and 1899. These collectibles often resemble silver dollars in size and design, making them popular among numismatists and historians alike.
