1911-S Lincoln Cent. MS-66 RD (PCGS).;A prime Registry Set candidate, this delightful pink-gold Gem displays excellent mint luster and crisp details throughout. The 1911-S issue, like other San Francisco minted cents of the era is scarce in Gem or finer, and opportunities to acquire examples finer than MS-65 with strong eye appeal do not come often. A real treat for the Lincoln cent specialist, this would serve with distinction in the finest of sets.
