So-Called Dollars are a type of medal or token that commemorates events, people, or places in the United States and are often produced in conjunction with significant anniversaries or celebrations. The 1954 So-Called Dollar is notable for its association with the opening of the 1954-55 New York World's Fair. These pieces typically feature designs that pay homage to various aspects of American culture or history and are part of a broader category known as exonumia, which includes items other than coins used as currency. Collectors often seek them out for their historical significance and unique designs.
