So-Called Dollars are a type of collectible medal often issued in connection with significant events or anniversaries, distinct from traditional currency. In the United States, a notable example is the 1919 So-Called Dollar, which commemorates the 1918 Armistice of World War I. These medals are typically made of various metals, including silver and bronze, and are valued by collectors for their historical significance and artistic design, rather than their face value. The 1919 edition is sought after due to its association with a pivotal moment in American and world history.
