1960-D Washington Quarter. MS-66 (PCGS). Blushes of warm rose-apricot, autumn-orange, blue-gray, golden-orange and silver-olive iridescence compete for dominance on both sides of this exciting Gem. Frosty surfaces are about as smooth as they come in a survivor of this conditionally challenging 1960s quarter issue. Mintage: 63,000,324 coins.
