1870-S $20 Liberty Gold Double Eagle AU-55 NGC

---

Struck in the post-Civil War era, this 1870 double eagle represents a fascinating moment in American currency. Minted in San Francisco, the coin contains nearly a full troy ounce of gold, specifically 0.9675 ounces, alloyed to a purity of 0.900. Its survival in such a well-preserved state makes it a compelling piece for study, carrying the distinct 'S' mint mark of the Western facility. The obverse features a left-facing portrait of Liberty, her hair bound by a band clearly inscribed with her name. A ring of thirteen stars encircles her profile, symbolizing the original colonies. On the reverse, a detailed heraldic eagle shields its chest, positioned beneath a canopy of thirteen stars and the national motto. The outer edge is inscribed with 'United States of America' and the twenty-dollar denomination, rendered as 'Twenty D.' This specific coin has been certified and graded in About Uncirculated 55 (AU-55) condition, preserving the intricate details of its nineteenth-century craftsmanship.
