About This Coin

The 1966 Washington Quarter is a United States quarter from the Washington Clad and Silver Proof Quarters 1965-1998 series — the second year of the series. In 1966, coins were struck at the Philadelphia Mint with a combined mintage of 823.3 million. This ranks 10th of 32 years by total mintage, below the series median of 1.2 billion. The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon and the reverse displays an eagle perched on a bundle of arrows with olive branches below. Struck after the transition from silver to clad coinage, as the Mint adapted to modern production methods and record-breaking mintages. Struck in 75% copper, 25% nickel over a pure copper center, weighing 5.67 grams, 24.3 mm in diameter, with a reeded edge. Collectors have cataloged 9 known die varieties for this date across 5 categories, including atypical die clash, cud, doubled die obverse and 2 other types. Produced 3 years before the celebrated 1969 key date. Across its variants, estimated values range from $0 to $9 depending on mint mark, grade, and strike type. A notable auction result reached $3.7K in MS67 grade at Heritage Auctions. Designed by John Flanagan.
