How to find the S mint mark

On a 1917-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 1917-S Mercury Dime valuable

With 27,330,000 struck, the 1917-S Mercury Dime is one of the more available dates of its series. Its value rests on metal content and condition rather than absolute rarity, which makes it an ideal type coin.

Every 1917-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 1917-S Mercury Dime. The 1916-D, with just 264,000 pieces struck in Denver before dime production shifted to quarters, is the key that defines the series; even heavily worn examples command four figures. 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 1917-S Mercury Dime is valued between $2.70 and $26.50 as of 2026-06-15. Estimates combine mintage rarity, key-date status and metal content; they are editorial guidance, not an offer to buy.
