The coin in question is a unique piece from the So-Called Dollars series, specifically referenced in Hibler & Kappen, with a year of minting noted as 1921. This series is known for commemorating significant events or figures in American history through artistic designs on coins, often reminiscent of traditional dollars. As a novelty item, the coin does not have an established diameter or weight, both recorded as '0.00000000', which raises questions about its physical dimensions; this might suggest it is either a prototype or a commemorative item that was not meant for general circulation. The mint of origin is also listed as 'Unknown', which is not uncommon for items in this series, particularly if they were privately produced or struck in small quantities. The denomination is classified as 'Other / Varied', indicating it may not conform to standard monetary values typically associated with national currency. Additionally, the production type is a 'Mint Strike', which confirms that this piece was produced through a formal striking process, commonly used for collectible issues. Despite the noted mintage being '0', this could imply that no known examples of this coin were officially produced or that it is an extremely rare piece likely tied to specific events or promotions. Overall, this 1921 So-Called Dollar represents a fascinating aspect of American numismatic history, appealing to collectors interested in unique commemorative pieces, even if its physical characteristics remain undefined.
