1860-S

The 1860-S is the seventh-year San Francisco eagle and one of the most uncompromising rarities of the No Motto branch series, just 5,000 pieces struck, smaller than every preceding S-mint $10 except the inaugural 1854-S. The delivery reflects the same pattern that defines the late 1850s at this mint: western gold was routed almost entirely into double eagles for Pacific commerce and Asian export, leaving the ten-dollar denomination as an afterthought. The entire mintage went into immediate circulation, and survivorship reflects that punishing trajectory. Doug Winter estimates only 35 to 45 examples survive across all grades, with fewer than ten properly graded About Uncirculated coins and just two confirmed Mint State pieces, making this date materially harder to locate than its small mintage alone would suggest.

Authentication should confirm the statutory 16.718-gram weight and specific gravity near 17.2, with the S mintmark below the eagle's tail examined for tooling or evidence of transplant from a common Philadelphia 1860. Strike on genuine survivors is typically soft, with weakness across the obverse stars and softness in the central reverse, a diagnostic of the issue rather than a grade defect. Most pieces show heavy, uniform wear consistent with extended circulation through the early Civil War economy. Original surfaces carry meaningful premium: many AU and finer coins have been lightly cleaned or dipped, and a problem-free EF40 with honest skin generally represents better value than a polished AU. PCGS or NGC certification is essential at any serious price level.

The collecting landscape places the 1860-S firmly at the top of the San Francisco Liberty Eagle hierarchy, just below the 1864-S. The finest known is an NGC MS62 that realized $36,800 at Stack's in September 2006, with a second Mint State piece, recovered from the S.S. Republic shipwreck, bringing the same $36,800 at Superior in May 2008. Below Mint State, AU examples appear only every few years and typically command strong five-figure results, while problem-free EF pieces trade in the upper four figures to low five figures depending on eye appeal. For the type collector building the No Motto S-mint run, the 1860-S sits with the 1855-S, 1858-S, and 1859-S as the genuine condition rarities that define difficulty in this branch.
