So-Called Dollars refer to a category of medals and tokens issued primarily in the United States, often commemorating a significant event or historical figure. They are typically made of silver or copper and were popularized in the late 19th and early 20th centuries. The term "So-Called Dollar" was coined by the numismatist Hibbert Newton in 1869, though the origins of the type can be traced back to earlier pieces, including those from 1778. These collectibles often feature intricate designs and serve as an important part of American numismatic history, appealing to both collectors and historians alike.
