This unique coin is a pattern or trial piece from the United States, specifically struck at the Philadelphia Mint. It is a 25¢ denomination piece, crafted from copper. The coin stands out due to its extremely limited mintage—only one specimen exists, making it a singular item of interest for collectors and numismatists alike. Despite the absence of a designated year, diameter, and weight, the coin can be categorized under the broader classification of "Coins" within the Patterns & Trial Coins series. The edge of the coin features a plain design, which is characteristic of certain trial pieces. Additionally, this coin lacks a designer attribution and mint mark, further enhancing its distinctiveness within the numismatic world. It holds significant historical and collectible value, particularly as it is a product of the United States of America, a country known for its rich coinage history. Given its unique properties and extreme rarity, this coin is likely an exceptional find for any serious coin collector.
