1870-S Liberty Head Eagle. EF-40 (NGC). Dominant honey-gold patina with glints of reddish-rose in the protected areas around the design elements. A touch of glossiness to the texture is noted for accuracy, but remnants of original luster are very much in evidence on both sides. The 1870-S is one of many unsung rarities in the Liberty Head eagle series, with just 8,000 pieces produced. As with all San Francisco Mint eagles of the Civil War and Reconstruction eras, the 1870-S circulated extensively and suffered a correspondingly high rate of attrition. Of the 80 to 100 survivors accounted for at <em>PCGS CoinFacts</em>, most grade no finer than VF. The Eliasberg-Bass specimen is unique in Mint State. This pleasing EF represents a significant find for the advanced gold enthusiast.
