1907-S

The 1907-S Barber dime sits in the comfortable middle of San Francisco's Barber output. Charles E. Barber's Liberty Head design, struck in 90% silver at 2.50 grams and 17.9mm with a reeded edge, ran in this series from 1892 through 1916. The reported mintage of 3,178,470 is healthy by branch-mint standards and places this date well below the volume of the 1907 Philadelphia issue while still landing far above the recognized San Francisco rarities such as 1896-S, 1901-S, and 1903-S. That mid-range posture is the defining trait: 1907-S is neither common enough to dismiss nor scarce enough to chase in well-circulated grades.

Strike quality on this issue is typical of early-twentieth-century San Francisco Barber production. Look first at the high points of Liberty's hair above the ear and forehead and at the leaves of the wreath on the reverse, since these areas surrender detail before any wear is genuinely present. The S mintmark sits below the wreath on the reverse and should be a small, well-formed serif punch resting cleanly on the field. Authenticators flag two patterns on dimes of this period. First, the coin should land within roughly 2.45 to 2.55 grams; a piece that falls notably outside that window is usually plated, polished, or a contemporary counterfeit. Second, an added S mintmark, occasionally encountered on the scarcer dates, will typically show a soldering halo, a tilted attachment, or a font that does not match official San Francisco punches of the era. Professional grading services PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) document the legitimate punch style.

For year-set collectors assembling 1907 dimes, the S branch is one of four pieces alongside Philadelphia, Denver, and New Orleans, and it is generally the second-most-affordable of the group in mid-circulated condition. Original surfaces matter more than sharpness here; a problem-free F or VF coin with even gray toning will hold its place in a Barber set far better than a cleaned higher grade. Collectors who want broader context can consult the Barber Dimes (Liberty Head) series history.
