1955-D Washington Quarter. MS-67 (PCGS).This exquisite Superb Gem exhibits sweeping crescents of vivid multicolored toning around the peripheries that yield to off-center swirls of pinkish-silver tinting in and around the centers. Sharply struck, expertly preserved, and easily the most desirable example of the issue that we have ever had the privilege of bringing to auction. With only 3,182,400 coins struck, the 1955-D has the lowest mintage of any circulation strike Washington quarter from 1941 through the end of the classic 90% silver series in 1964. This offering represents only the second at auction for the issue in PCGS MS-67, and it will surely catch the eye of discerning collectors.PCGS# 5859.
