The coin in question is a Seated Liberty Dime, minted in San Francisco in the year 1885. This particular piece carries the denomination of ten cents, also known as a dime, and is composed of silver, which is significant given the historical context of U.S. coinage. With a mintage of only 43,690, the 1885-S Seated Liberty Dime is considered relatively rare, making it a sought-after item among collectors. The coin features a diameter of 17.9 millimeters and a weight of 2.5 grams, adhering to the specifications for dimes of that era. As part of the Seated Liberty series, this dime showcases the iconic design that reflects the artistic style of the mid-to-late 19th century, with Lady Liberty seated and the denomination clearly marked. The absence of specific dimensions for width and height indicates a focus on its circular nature. Given its low mintage and historical significance, this coin might hold a considerable value in the numismatic market, especially for those seeking to complete their collections. The coin’s characteristics—the mint mark "S" denoting its origin from the San Francisco Mint, alongside its pristine material of silver—enhance its appeal and collectibility in the world of American coins.
