The coin in question is a remarkable example of American numismatic history, specifically the Flying Eagle Cent series, which was struck in 1856. This particular coin is notable for being a proof issue, produced at the Philadelphia Mint, and is made from a copper-nickel alloy. Identified by its denomination of 1¢ (one cent), this coin has a diameter of 19 mm and weighs approximately 4.67 grams. It carries the distinctive "P" mint mark, indicating its origin from the Philadelphia Mint, which is significant as many collectors seek coins from this historic mint. The mintage of this series is quite limited, with only 2,500 pieces produced in 1856, making it a highly sought-after item among collectors. Its age—dating back over 160 years—along with its exquisite design and low production numbers, contribute to its desirability. In terms of condition, coins of this caliber are typically kept in pristine condition, often graded on a scale from Poor to Mint State, with proof coins like this one generally falling within the higher grading tiers due to their intended purpose for collectors and presentation. As a noteworthy piece of American currency history, this 1856 Flying Eagle Cent stands out, not just because of its age and rarity, but also for representing a transitional period in U.S. coinage design, marking the shift from the earlier large cents to the smaller, more modern coins. Collectors and enthusiasts alike value such coins for their historical significance and aesthetic beauty.
