The coin in question is a Proof Seated Liberty Dime, struck in 1873. Designed by the renowned engraver James Barton Longacre, this particular dime is notable for its high-quality minting process, resulting in a beautiful finish that characterizes Proof coins. Measuring 17.9 mm in diameter, this dime is composed of 90% silver and 10% copper, showcasing the traditional composition of U.S. coins from this era. With a weight of 2.48 grams, it features a reeded edge, which not only serves as a decorative element but also helps to deter counterfeiting by making it more difficult to shave metal off the edges. Produced without a mint mark, this 1873 Seated Liberty Dime is part of a limited mintage of just 1,100 pieces, making it a rare find for collectors. The denomination is listed at $3, which is an unusual designation for a dime and reflects the historical context of coinage during that period. Overall, this coin represents both a significant piece of numismatic history and a fine example of American coinage artistry. Its rarity, combined with its intricate design and historical importance, makes it a valuable addition to any collection.
