The coin described is a Barber Half Dollar, which was minted in 1892 at the New Orleans Mint, denoted by the 'O' mint mark. This coin features a denomination of 50 cents, making it a half dollar and is composed of silver. The Barber series, designed by Charles E. Barber, is known for its classic and elegant design, which includes a depiction of Liberty on the obverse and an eagle on the reverse. Measuring approximately 30.6 millimeters in diameter and weighing 12.5 grams, this half dollar is part of a mintage of 390,000 coins, making it a more common issue from the series, yet still a cherished piece among collectors. While the coin’s actual dimensions are marked as zero in width and height, its standard specifications indicate that it has a round, flat shape typical of coins. The Barber Half Dollar represents not only a piece of currency but also an important part of American numismatic history, reflecting the artistry and craftsmanship of late 19th-century coinage. Being part of the circulating currency of its time, it serves as a reminder of the economic context of the 1890s in the United States. As a collectible item, the condition and market demand for this specific year and mint mark can significantly influence its value among enthusiasts and collectors.
