So-Called Dollars are a category of collectible coins and medallic items, often issued to commemorate specific events or people rather than as legal tender. The term was popularized by coin dealers Hibler and Kappen in their reference book, which catalogs various issues of these items. Focusing on the year 1955, collectors may encounter specific pieces from this era that hold significance due to their design, rarity, or historical context, although many remain of unknown provenance or significance within the broader numismatic landscape. These items often appeal to collectors interested in the intersection of numismatics and commemorative art.
