So-Called Dollars are a category of collectibles that typically refer to medallions or tokens issued to commemorate events or people, particularly in the United States. The term originates from the 19th century when these pieces were produced alongside official coinage but lacked legal tender status. The Hibler-Kappen catalog, published in the 20th century, is a comprehensive reference that identifies and catalogs many of these items, including examples from 1953. The classification includes various designs and materials, with some pieces gaining significant historical and numismatic value among collectors.
