1920-S Standing Liberty Quarter. MS-67 (PCGS). CAC. Both sides of this beautifully toned Superb Gem display vivid multicolored toning that include shades of red, gold, emerald green, apricot and salmon pink. The surface preservation is no less impressive than the eye appeal, as both sides are silky smooth and frosty. With a relatively modest mintage of 6,380,000 coins, the 1920-S is one of the semi-key date Standing Liberty quarters and a difficult issue to find with a Full Head designation. The present example is tied for finest certified at PCGS in its category. Its superior technical quality and immense eye appeal ensure that it will sell for a strong premium to an advanced Standing Liberty quarter or toning enthusiast.
