The coin in question is a Seated Liberty Half Dime, minted in 1844 at the Philadelphia Mint. This particular piece is notable for its status as a Proof coin, which indicates that it was struck with special care to produce a high-quality finish, resulting in a mirror-like appearance and sharp details. The denomination of this coin is 5 cents, reflecting its value as a Half Dime, and it is crafted from silver, a characteristic material of the era. Recognized for its traditional diameter of 15.5 millimeters and a weight of 1.34 grams, this coin represents an important facet of American numismatics, especially within the context of its series. While the mintage figure is recorded as '0', it is essential to understand this typically refers to the absence of recorded production numbers for the Proof version of the coin, making it potentially rarer and more desirable among collectors. Overall, the 1844 Seated Liberty Half Dime combines historical significance, artistic design, and numismatic rarity, making it a prized item for enthusiasts of American coins and those focused on the Seated Liberty series.
