So-Called Dollars are a type of numismatic item that are not official U.S. currency but are categorized as medals or tokens often commemorating events or people. The 1918 So-Called Dollar references various medal designs produced to celebrate specific occasions, particularly related to World War I. These pieces typically feature imagery and inscriptions that capture historical significance, and they are sought after by collectors for their artistic value and historical context. The phrase "One Dollar" might be inscribed to lend a sense of formality or to categorize the item within the context of U.S. monetary values, though they do not carry legal tender status.
