So-Called Dollars are a category of collectible medals issued primarily in the United States, often for commemorative purposes. They typically feature designs that celebrate significant events, individuals, or organizations, and were produced in various metals, including silver and bronze. The term "So-Called Dollars" originates from a book by Hibler and Kappen published in the mid-20th century, which cataloged these items. The year 1921 is notable for several such medals, often reflecting the societal or historical themes of that period.
