So-Called Dollars are commemorative medals or tokens that are often associated with specific events or themes but do not have legal tender status. In the United States, these pieces emerged notably in the late 19th and early 20th centuries, with many created to commemorate exhibitions, anniversaries, or significant historical events. Though titled "dollars," they are not recognized as official currency like the U.S. one-dollar coin. Collectors value So-Called Dollars for their historical significance, artistic design, and the stories they tell about American culture and heritage.
