The coin in question is a highly sought-after example of the Coronet Head Cents series, specifically minted in 1837 at the Philadelphia mint. This $10 piece, designed by the well-known engraver Robert Scot, is remarkable not only for its denomination but also for its exemplary production as a proof coin, indicating it was struck with particular care and precision. The coin has a diameter of 28 mm and a weight of 10.89 grams, characteristic of the high-quality coins produced in that era. Its edge is plain, which is typical of many coins from this period, and it is composed of copper, a common material used in early U.S. coinage. Notably, the mintage for this particular coin is quite low, with only 8 pieces produced, making it an exceptional rarity in the numismatic world. This low production number adds to its value and desirability among collectors. The lack of a mint mark on this coin signifies that it was struck in Philadelphia, which is the original mint for U.S. coinage. Overall, this 1837 Coronet Head $10 proof coin is a striking piece of American history, reflecting the artistry and craftsmanship of its time, along with its valuable status as a rare collectible.
