So-Called Dollars refer to a category of commemorative tokens and medals that were issued primarily in the United States to celebrate various events, anniversaries, or individuals. Although they are often designed in a dollar coin format, they are not official currency and typically lack the legal tender status of government-issued coins. The term "So-Called Dollar" was coined in the 1930s, and one notable example from 1920 includes pieces commemorating events like the 1920 Democratic National Convention or the Panama-Pacific International Exposition. These collectors' items can vary in material, design, and rarity, making them popular among numismatists.
