So-Called Dollars are a category of commemorative and other types of medals that were produced in the United States, particularly during the late 19th and early 20th centuries. These pieces often feature designs commemorating specific events, people, or places and were typically made from silver or other metals. The term "So-Called Dollars" refers to their nominal value of one dollar, although they were not intended for circulation as currency. The 1900 So-Called Dollars are notable for their historical significance and collectible appeal among numismatists.
