The Mercury Dime, officially known as the Winged Liberty Head dime, was produced by the United States Mint from 1916 to 1945. The design features a portrayal of Liberty wearing a Phrygian cap on the obverse and an olive branch and fasces on the reverse. The 1931-S Mercury Dime is particularly noteworthy among collectors due to its low mintage of only 436,800 coins, making it a key date in the series and highly sought after for its rarity and historical significance.
