So-Called Dollars refer to a specific type of medal or coin-like item that commemorates events, individuals, or organizations but are not official currency. The term originated from a series of pieces created in the United States during the 19th century, notably around the 1875 centennial celebrations. These items often feature intricate designs and were produced by private mints or organizations. The designation "SC 1" typically refers to the first entry in the reference catalog for these tokens, indicating its significance and prominence within the So-Called Dollar collection.
