So-Called Dollars are commemorative medallions or tokens that were issued primarily in the United States around the time of significant events or anniversaries, particularly during the late 19th and early 20th centuries. The term refers to pieces that resemble the size and shape of a dollar coin. The 1931 So-Called Dollar, a notable example, was issued to commemorate the 200th anniversary of the birth of George Washington. These pieces are collectible and can be found in various materials, including silver and bronze, often reflecting the historical context of their issuance.
