The 1966 Washington Quarter is a 25-cent coin issued by the United States Mint as part of the Washington Quarter series, which began in 1932 to honor George Washington. Composed primarily of a copper-nickel alloy, the 1966 quarter features a portrait of Washington on the obverse and an eagle on the reverse. This coin does not contain silver, as the transition to a purely copper-nickel composition occurred in 1965. Collectors seek the 1966 Washington Quarter for its historical significance and as a part of the larger collection of 20th-century U.S. coins.
