1863-S

San Francisco struck 157,500 Seated Liberty dimes in 1863, the third year of Legend obverse production at the branch and the principal circulation-strike Seated dime for daily commerce during the year. With Philadelphia operating at the extraordinary low of 14,460 pieces under the Civil War silver hoard, and with New Orleans out of federal hands since 1861, the San Francisco coinage carried effectively all of the country's daily-use Seated dime supply through the year. Pacific Coast commerce continued to function on a hard-money basis, with gold and silver coins changing hands at face value while the eastern economy ran on greenbacks and fractional currency. The 1863-S mintage represents a small drop from the 180,750-piece 1862-S, reflecting a routine adjustment to branch planchet allocation rather than a Civil War demand collapse on the West Coast. The 2.49-gram weight standard remained, and the S mintmark stayed inside the wreath on the reverse.

Strike quality on the year shows the recurring early Legend-era San Francisco pattern. The obverse usually comes up cleanly on Liberty's head and the upper legend lettering on early-state dies, with softness arriving on the central reverse wreath leaves and the lower obverse lettering as working dies aged into late states. Survival is broader across grades than the small mintage might suggest, reflecting active West Coast commerce that did circulate these pieces. Most documented examples fall in Good through Very Fine; Extremely Fine and About Uncirculated coins surface with patience, and Mint State examples are scarcer than mid-circulated pieces but exist in modest numbers above MS62. Authentication runs through the 2.49-gram weight, the 17.9-millimeter reeded edge, the Legend obverse signature, and the S mintmark inside the wreath. Altered-mintmark counterfeits (an S added to a Philadelphia 1863) typically miss the proper punch depth and lateral position, though they require careful side-by-side comparison against documented genuine examples.

For collectors, the 1863-S reads as a Semi-Key with strong historical anchor: the principal circulating Seated dime of the third Civil War year and a meaningful date in any early Legend-era San Francisco run. Circulated examples through Very Fine command moderate premiums, and certified pieces above Extremely Fine require both patience and budget to acquire problem-free.
