The coin in question is a unique piece pertaining to the category of "So-Called Dollars" as classified by Hibler and Kappen. Minted in 1879, it represents a fascinating part of numismatic history associated with the United States. Unfortunately, the specific mint responsible for its production is unknown, adding an element of mystery to its provenance. Despite its classification as a coin, the denomination is marked as 'Other / Varied,' indicating that it does not conform to commonly recognized denominations of the time. This, coupled with a recorded mintage of zero, suggests that this coin might not have been widely circulated or that it could have been struck in extremely limited quantities, potentially qualifying it as a unique or highly collectible item. The properties of the coin regarding diameter and weight are listed as '0.00000000,' which may imply either a lack of detailed measurement data or an error in documentation. Moreover, the coin is identified as a 'Proof' type, suggesting that it was likely struck using special dies to achieve a higher quality finish, typically intended for collectors rather than general circulation. Overall, this coin represents an intriguing aspect of U.S. numismatic heritage, offering collectors a glimpse into the artistic and monetary practices of the late 19th century, despite the absence of concrete measurements and mintage figures. Its classification within the So-Called Dollars series also signifies its potential appeal to advanced collectors and enthusiasts of specialized coinage.
