The coin in question is a notable example from the United States, minted in 1856, and falls under the category of "Patterns & Trial Coins." This unique coin features the Philadelphia mint mark 'P,' signifying its origin from the Philadelphia Mint, which is one of the oldest and most historically significant mints in the United States. As a trial or pattern piece, it was likely created to test new designs or preparation methods before progressing to mass production, making it an intriguing addition to any numismatic collection. The coin is categorized under "Other / Varied" denominations, indicating that it might not fit the traditional expectations of currency. While specific physical measurements like width, height, diameter, and weight are not provided, it is essential to note that qualities such as these often play a significant role in determining a coin's grade and value. The coin was produced as a proof, which suggests a higher quality finish typically sought after by collectors. Despite the absence of mintage data—and specific attributes like size and weight—the coin holds great historical significance, especially within the context of U.S. numismatics. The production of 1856 trial coins reflects the evolving nature of American currency during that period, making this coin not only a collectible artifact but also an important piece of American monetary history. Given its potential rarity and historical implications, it holds substantial appeal for both collectors and historians alike.
