1912-S

The 1912-S Barber dime came out of San Francisco with a business-strike mintage of 3,420,000 pieces, a figure that places this issue in the middle tier of S-mint output across the series. San Francisco produced Barber dimes at widely varying volumes between 1892 and 1916, with several early years dipping below one million and creating the famous S-mint rarities. The 1912-S sits well above that scarce-date threshold but under the high-volume Philadelphia mintage of the same year. By 1912 Charles E. Barber's Liberty Head design had been in production for two decades, and routines at the facility were fully matured. The coin weighs 2.50 grams, measures 17.9 millimeters across, carries a reeded edge, and is struck in 90 percent silver.

Strike quality on the 1912-S is generally acceptable for a late-series S-mint Barber dime, with central detail on Liberty's headband and the reverse wreath the usual diagnostic for grade assignment. Lettering on the LIBERTY headband is the most important wear indicator on every Barber dime. The S mintmark on a genuine 1912-S is a small, rounded letter seated beneath the wreath ribbon on the reverse. Because the 1912 Philadelphia issue had a mintage above 19 million and trades at a small fraction of the 1912-S price in mid grades, the standard authentication concern is an added-S mintmark on a Philadelphia host coin. Examine the mintmark under magnification for surface continuity with the field and clean metal flow around the base; tooling marks or a faint seam point to a transplant. PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) both certify the issue without unusual notation, and a confirmed weight near 2.50 grams remains a useful first filter.

Within a date and mintmark set, the 1912-S occupies a middle slot in the 1912 year-set, scarcer than its Philadelphia and Denver counterparts but short of the sub-million S-mint rarities that anchor the series. Circulated examples in Good through Fine are obtainable for a modest premium over common dates, and Very Fine to Extremely Fine pieces reach the market with patience. Choice Mint State coins are the genuine condition challenge, with original luster and clean cheek surfaces commanding strong premiums in MS-63 and finer.
