So-Called Dollars refer to a category of medals and tokens that were issued primarily as souvenirs or commemoratives but are not legal tender. The term originated from pieces struck in connection with events, fairs, or significant anniversaries, particularly in the United States. The 1959 So-Called Dollar, often associated with the 1959-1960 New York World's Fair, typically features designs that celebrate American culture, innovation, or historical events. Collectors value these pieces for their artistic representation and historical significance, making them a sought-after item in numismatic circles.
