1877-S $20 Liberty Gold Double Eagle MS-61 NGC

---

In 1877, the San Francisco Mint struck a significant run of twenty dollar gold pieces, totaling 1,735,000 coins. These heavy gold coins, containing nearly a full troy ounce of pure gold (0.9675 ounces), served as a backbone of commerce in the American West. Each piece was composed of a durable 90 percent gold alloy, designed to withstand the rigors of circulation during a bustling era of expansion. This specific specimen has survived the decades in an exceptional state of preservation, earning a certified grade of Mint State 61 (MS-61). Bearing the distinctive 'S' mint mark on the reverse, the coin stands as a fascinating physical survivor from the late nineteenth century, offering onlookers a direct window into the artistry and industrial output of the historic California mint.
