1861-S

The 1861-S Seated Liberty Half Dollar carries a wartime story that the date alone cannot tell. San Francisco struck 939,500 pieces this year, the branch's highest half dollar output to date and a figure that mattered far beyond the Pacific coast. While the eastern economy convulsed through the first months of the Civil War and Treasury suspension of specie payments by year's end drove silver and gold into hoards from Boston to St. Louis, San Francisco continued normal operations under Union authority and California's hard-money tradition. By mid-1862 the branch was effectively the only U.S. mint placing fresh silver into circulation, since Philadelphia's coinage was hoarded almost as fast as it left the press and the New Orleans facility had passed out of federal hands the previous winter. Every 1861-S that entered Pacific commerce did so as one of the few federal silver pieces still moving at face value anywhere in the country.

Strike character on the issue follows the established San Francisco pattern, with softness recurring on Liberty's head, the upper shield lines, and the central reverse where extended die life from the heavy production run produced visible erosion on later-state survivors. Authentication starts at the standard weight of 12.44 grams and 30.6-millimeter diameter; the "S" mintmark sits below the eagle and should rise naturally from undisturbed reverse field, since added-mintmark fakes built from common 1861 Philadelphia coins remain a known trap on branch-mint Seated halves. Wiley-Bugert catalog ten die marriages (WB-1 through WB-10) for the date, using six obverse dies paired with both Medium S and Large S reverse mintmarks, and a legitimate example's reverse die markers, mintmark size and placement, and obverse polish lines should match a documented pairing. Grade distribution favors Very Good through Very Fine, with About Uncirculated and Mint State coins genuine condition rarities given the issue's full circulation service on the Pacific coast.

For collectors, the 1861-S is a moderately available branch-mint date with outsized historical resonance as wartime silver supply. For the design's full arc and the Civil War context that frames this issue, see the Seated Liberty Half Dollar series history.
