So-Called Dollars are a type of collectible coin that represents medals or tokens issued to commemorate specific events, places, or individuals, often related to the United States. The Hibler-Kappen catalog, first published in the 1960s, provides a comprehensive listing of these items, including those from 1961 and beyond. The term "So-Called Dollar" originated from these pieces' similarity in size to a dollar coin, though they are not considered legal tender. The classification "Unknown" may refer to specific pieces whose origins or significance have not been fully documented or identified within the hobby.
