So-Called Dollars are a type of commemorative medal that typically celebrate events, anniversaries, or notable people, rather than being official currency. The term originates from the late 19th century and encompasses a variety of tokens, medals, and non-official dollar-like items. The Hibler-Kappen catalog is a reference book that catalogs these So-Called Dollars, with the 1951 edition detailing a range of pieces produced around that time. These collectibles are often sought after by numismatists for their historical significance and unique designs.
