1952-D Washington Quarter. MS-67 (PCGS). Toned in bold smoky mauve-gray and reddish-copper patina, this Superb Gem also displays vivid undertones of multicolored iridescence. Despite a mintage of 49,795,200 coins, the 1952-D is surprisingly elusive in the finest Mint State grades, as here. A find for both astute Washington quarter collectors and toning enthusiasts.
