How to find the S mint mark
On a 1931-S Mercury Dime, the "S" mint mark of the San Francisco Mint sits on the reverse, to the right of the fasces base, left of the E in ONE. A loupe helps: on worn examples the letter can fade into the surrounding devices.
What makes the 1931-S Mercury Dime valuable
The mintage of 1,800,000 puts the 1931-S Mercury Dime among the scarcer issues of its series. It is findable, but nice examples take patience, and the market prices that difficulty in.
Every 1931-S Mercury Dime contains 0.0723 troy ounces of pure silver, currently worth $2.64. That intrinsic value is a hard floor under the price: no matter how worn the coin, the silver inside cannot be graded away.
Context adds the final layer to the 1931-S Mercury Dime. Adolph Weinman's Winged Liberty dime earned its enduring nickname from the public, who mistook Liberty's winged cap, symbolizing freedom of thought, for the Roman god Mercury. Owning this date means owning a piece of that story, and demand for the series as a whole sustains liquidity for every issue in it.
Summary: the 1931-S Mercury Dime is valued between $4.95 and $231 as of 2026-06-15. Estimates combine mintage rarity, key-date status and metal content; they are editorial guidance, not an offer to buy.
