The coin in question is a unique piece from the United States, specifically a 10¢ trial piece from the year 1866. It falls under the category of Patterns & Trial Coins, indicating that it was likely produced as a prototype or experimental issue by the Philadelphia Mint. This coin is characterized as having a Proof production type, which means it was struck using specialized processes to create a high-quality finish, often for collectors rather than for circulation. Despite the lack of specific dimensions and weight, the coin is categorized under standard coin properties, which typically would include a defined diameter and weight. The designer is not specified, which may be common for trial pieces that did not enter full production. Notably, this particular coin does not carry a mint mark, indicating that it was produced in Philadelphia. Additionally, its mintage is recorded as zero, suggesting that either it was not produced in quantity or the records do not show any mintage, which adds to its uniqueness and potentially increases its desirability among collectors.

Its status as a Proof trial coin further enhances its appeal for numismatists and collectors interested in historical American currency.
