1866-S $10 Liberty Gold Eagle AU-55+ PCGS (Motto)

---

In 1866, the San Francisco Mint struck a remarkably small run of ten-dollar gold pieces, totaling just 11,500 coins. This particular era marked a transition in the design of the Liberty Gold Eagle series, featuring the inclusion of the religious motto on the reverse. Finding an example from this limited West Coast production that has survived the decades in such exceptional quality is a notable event for numismatic enthusiasts. This specimen is certified in About Uncirculated (AU-55+) condition, retaining much of its original luster and detail. Struck from 0.900 fine gold, the coin contains 0.4838 troy ounces of precious metal. The obverse showcases the classic profile of Liberty wearing a coronet inscribed with her name, surrounded by thirteen stars and the 1866 date. The reverse displays the heraldic eagle with the 'S' mintmark beneath, denoting its origin at the San Francisco facility.
