So-Called Dollars are a category of collectable medals that were produced to commemorate events, places, or individuals, often related to the United States. The term "So-Called Dollar" originated from a reference to these pieces as being similar in size to a U.S. silver dollar but not being legal tender. The 1897 So-Called Dollar, specifically, is notable for commemorating the 1897 Pan-American Exposition held in Buffalo, New York. It is often sought after by collectors for its historical significance and the artistry of its design.
