So-Called Dollars are a type of collectible coin or medal that commemorates significant events, places, or individuals, often issued by private entities or the government. The term "So-Called" originates from a book by Hibler and Kappen published in 1951, which cataloged these items, primarily focusing on pieces that are not official U.S. coinage but are still recognized by collectors. These can vary widely in design, composition, and value, often sought after for their historical significance and collectible appeal.
