The coin in question is a Seated Liberty Quarter minted in 1874 at the Philadelphia Mint. It boasts a denomination of 25 cents (commonly known as a quarter) and is part of the United States of America currency. This particular example is noteworthy for being a proof coin, which typically signifies a higher quality of minting, often intended for collectors and not for general circulation. The coin features a diameter of 24.3 mm and a weight of 6.25 grams, constructed from silver, which adds to its intrinsic value. The production mintage for this specific year and type is notably limited, with only 700 coins struck, making it a rare find for numismatists and collectors alike. Despite the designated width and height properties listed as 0.00000000, this does not detract from the significant attributes of the coin. The design showcases the iconic Seated Liberty motif, which is recognized for its artistic representation of Lady Liberty seated, as well as the detailed engravings that highlight the craftsmanship of the era. Overall, this 1874 Seated Liberty Quarter serves not only as a monetary piece but also as a historical artifact, representing a moment in American history with its unique qualities and limited mintage, ideal for both collectors and enthusiasts in the world of numismatics.
