So-Called Dollars are a type of commemorative medal or medallion that were issued to mark significant events or individuals, often closely related to the US dollar in size and theme. Originating in the United States during the 19th century, with a notable example in 1879, these pieces typically featured inscriptions and imagery that commemorated political, social, or cultural events. While not official currency, So-Called Dollars are collectible due to their historical significance, artistry, and the stories they tell about American history and celebration. The term "So-Called Dollar" was popularized by numismatist Harold E. Hibler in his cataloging work on these medals.
