1961-D Washington Quarter. MS-66 (PCGS). Ringed in blue-gray and reddish-rose peripheral toning, the obverse center displays softer golden-olive iridescence. The reverse is brilliant, and both sides have full mint luster. Elusive any finer, the 1961-D is one of several surprising condition rarities from the later 90% silver Washington quarter series. Mintage: 83,656,928 coins.
