Barber Dimes are a type of coin struck by the United States Mint from 1892 to 1916, designed by Charles E. Barber. The 1909 Barber Dime, particularly from the San Francisco mint (S mint mark), is of interest to collectors due to its limited mintage and historical significance. This ten-cent piece is composed of 90% silver and 10% copper, and it showcases intricate details of Liberty on the obverse and an eagle on the reverse. The 1909-S Barber Dime is considered a key date in the series, making it highly sought after by numismatists.
