The coin in question is a unique piece from the Patterns & Trial Coins series, minted in Philadelphia in 1866. This particular coin is a 25-cent piece (25¢) and is noteworthy for being a proof strike, which signifies it was produced with high standards of quality and finish. The material of this coin is copper, which is quite distinctive for its time, as most circulating coins were made from different alloys. It's important to note that this coin does not have any specific designer associated with it, and it lacks a mint mark, indicating it was produced at the Philadelphia Mint, where many significant American coins were crafted. The mintage figure is recorded as zero, suggesting that this coin was likely never intended for general circulation and may have been produced under very limited circumstances, making it exceedingly rare. All dimensions related to the coin such as width, height, diameter, and weight are listed as zero, which may indicate that this information is either not recorded or not applicable in this context—perhaps due to its trial nature. The edge type is also marked as 'N/A', further emphasizing the special status of this coin, as it likely does not conform to standard coin edge characteristics. Given its features and rarity as a trial piece from 1866, this coin would hold significant value to collectors and numismatists, particularly those focused on American coinage history.
