Our modern age dollars include the Susan B Anthony, the Silver Eagle, Sacagawea, and the Presidential dollars. The “Susan B’s” caused the casinos in Vegas to begin using tokens. They previously were using the larger Eisenhower dollars. The small size of the Susan B caused it to fall victim to the “Edsel Syndrome”. The Silver Liberty got it’s design on the obverse from the Walking Liberty dollar designed by Adolph A. Weinman.
