So-Called Dollars refer to a category of commemorative coins and medals that were produced in the United States, particularly around the late 19th and early 20th centuries. The term is often used for items that commemorate events, people, or places but do not have legal tender status. An example is the 1878 One Dollar piece, which was part of a series created to commemorate specific events or figures, showcasing intricate designs and historical significance. These collectibles are sought after by numismatists for their artistic value and historical context.
