1875 Liberty Seated Quarter. MS-67 (PCGS). CAC. Secure Holder. This Philadelphia Mint issue had a hefty mintage of nearly 4.3 million pieces, but a surprisingly low number have survived in Mint State. This is a highly lustrous, conditionally rare Superb Gem example, with gorgeous sea-green, electric-blue, and rose toning over impressively preserved surfaces. One of just four coins graded as MS-67 by PCGS, with none finer.
