1964 Washington Quarter. MS-67+ (PCGS).Intense toning in salmon-pink, copper-apricot, sea-green, golden-olive and powder blue envelops both sides of this phenomenal Superb Gem. It is definitely one for the toning enthusiast. Production of quarters skyrocketed at both the Philadelphia and Denver mints in 1964, the former facility delivering over 500 million circulation strikes that year. Very few from that large mintage are as superb as this, however, either from technical or aesthetic standpoints. Unsurpassed in PCGS-certified grade, in fact, this beautiful Superb Gem should have no difficulty finding its way into another high ranked collection on the PCGS Set Registry.PCGS# 5876. NGC ID: 246U.From the Washington Rainbows Collection, the #1 PCGS Registry Set of Silver Washington Quarters, 1932-1964.
