The coin in question is a fascinating piece from the United States, specifically a trial or pattern coin with a denomination of 1¢, minted in 1867 in Philadelphia. It is noteworthy that this coin is part of the Patterns & Trial Coins series, which typically includes experimental pieces that were not intended for general circulation. The coin showcases a production type classified as "Proof," indicating that it was struck with precision and intended for collectors, displaying high-quality craftsmanship through its finish. Although it has no designer attributed to it, the era and series it belongs to are significant in the numismatic community, reflecting an important period in American coinage history. The coin does not carry any mint mark, a feature that sometimes distinguishes different mints, but its mintage is noted as zero, which implies that this particular piece may be indicative of a unique or specially made type due to its status as a pattern or trial coin. Interestingly, all measurements (height, width, diameter, and weight) have a value of 0.00000000, which suggests that this coin might be a conceptual representation or not yet physically made, further emphasizing its rarity and significance in the numismatic field. Overall, this 1867 Proof 1¢ trial coin serves as an extraordinary collector's item, illustrating the innovative practices in American coin design during the mid-19th century. While categorized as "Other" in material, its historical context and production type make it a prized piece for collectors of both patterns and American coinage alike.
