So-Called Dollars are a category of numismatic items often commemorating events, places, or notable figures, primarily produced as medals or tokens rather than official currency. The term originated from the book "So-Called Dollars" by Hibler and Kappen, published in 1963, which cataloged these pieces. The year 1857 marks the establishment of various commemorative tokens and medals in the U.S., reflecting a growing interest in numismatic collecting and the historical significance of the events they commemorate. Collectors of So-Called Dollars prize these items for their artistic designs and historical narratives associated with American culture and heritage.
