1911-S

The 1911-S Barber dime came out of the San Francisco Mint with a circulation mintage of 3,520,000 pieces, a figure that places this date in the middle band of branch-mint output for the 1892 through 1916 series. Production fell well below the 18,870,000 Philadelphia coins and the 11,209,000 Denver coins struck the same year, but it cleared the sub-million threshold that defines the genuine S-mint scarcities such as the 1895-S, 1896-S, and 1901-S. Charles E. Barber, Chief Engraver of the United States Mint, designed both sides, and by 1911 his Liberty Head design had been in continuous production for nineteen years. Each piece followed standard specifications of 2.50 grams, 17.9 millimeters in diameter, with a reeded edge and the standard 90 percent silver and 10 percent copper alloy.

Strike quality on the 1911-S typically runs from acceptable to soft, a familiar San Francisco pattern in late-series Barber production. Headband lettering on the obverse remains the principal wear and strike diagnostic, with all seven letters of LIBERTY fully formed serving as the benchmark that separates premium pieces from typical survivors at the same numerical grade. The upper laurel leaves and bow knot of the reverse wreath often show the earliest softness on weakly struck examples. Authentication centers on the mintmark, since the 1911 Philadelphia issue is roughly five times more plentiful and trades at a meaningful discount, creating a modest incentive for added-S deception. Inspect under at least 10x magnification for clean serif terminals, correct rounded form, and surface continuity with the surrounding field; an added mintmark often betrays a faint seam or tooling marks at its base. Confirm weight at 2.50 grams before considering surface markers. Examples certified by PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) bypass this concern.

Within a 1911 year set, the San Francisco strike sits between the high-mintage Philadelphia issue and the mid-range Denver coin, offering a representative branch entry without the cost of a recognized rarity. Circulated examples in Good through Fine remain readily available at major shows, Extremely Fine and About Uncirculated pieces require modest patience, and choice Mint State coins with original luster command the firmest premiums.
