1876-S

The 1876-S Liberty Head half eagle was struck during the United States Centennial year, but the celebration did not translate into busy gold production at the San Francisco Mint. The branch turned out only 4,000 half eagles for circulation, one of the smallest single-year mintages in the entire Coronet series and a figure that places this issue alongside the legendary 1864-S (3,888) as the lowest San Francisco half eagle deliveries on record. Monetary contraction after the Panic of 1873 and slowing California gold deposits suppressed output, while the same mint struck nearly 1.6 million double eagles for export. The Type 2 With Motto design carries IN GOD WE TRUST on a banner above the heraldic eagle, with the small S mintmark on the reverse. Companion San Francisco gold that year shared the squeeze: the quarter eagle and eagle were each capped at 5,000 pieces.

Authentication standards for this date are straightforward but unforgiving given the value at stake. A genuine 1876-S weighs 8.359 grams on a 21.6 mm planchet of 90% gold and 10% copper, with a reeded edge. Because added-mintmark forgeries built from common-date Philadelphia 1876 half eagles are the primary deception, the S punch position and shape deserve close attention: the mintmark sits cleanly below the eagle, with serifs and interior cavity matching other San Francisco gold of the period. Planchet weight under 8.30 grams or any disturbed metal around the mintmark area is an immediate red flag. Most surviving examples grade in the Fine to Extremely Fine range, with original mint luster typically muted by light circulation.

Survival is genuinely thin. Major grading services estimate 50 to 60 examples known across all grades, with the majority in VF and XF, only a small group in About Uncirculated, and Mint State pieces nearly nonexistent. That tight population has made the 1876-S one of the most chased San Francisco half eagle dates among advanced gold specialists, with prices that climb steeply from Fine through XF and reach commanding levels in any Choice condition. A PCGS XF45 example brought $84,000 at Heritage in 2016, and the date routinely outperforms its mintage at auction. For collectors building a date-and-mintmark set, 1876-S is one of the few issues whose absence is obvious. For background, see the Liberty Head Half Eagle series history.
