1966 was the second year after the Washington quarter’s composition changed from silver to copper-nickel. The Philadelphia mint was the only one in the US that produced quarters this year.
You can find pieces from regular strikes and those from the Special Mint Set intended for collectors. Both versions came without the mint mark. These coins are not among the expensive ones nowadays, but the 1966 quarter value can be higher for perfectly preserved specimens and rare error pieces.

History of the 1966 Washington Quarter
The US Mint issued Washington quarters for the first time in 1932 to celebrate 200 years of George Washington’s birth. Laura Gardin Frasewhile’s design won the competition after the Commission accepted it. Unfortunately, Mr. Mellon, Treasury Secretary at the time, chose John Flanagan’s design instead.
The designer’s creative solution was simple, and the thin relief made striking easier. On the other hand, the US Mint adjusted the design a few times, making coins with different Motto appearances. The initially issued Washington quarters were made of 90% silver, and their compound remained until 1964.
Due to the silver price increasing by that year, people hoarded coins, causing a significant shortage. The idea of minting more 1964 silver coins as a countermeasure reduced the silver stock even more.
Precious metal prices continued to rise, so Lyndon Johnson, the then-US President, announced the silver elimination from quarters and dimes. Therefore, silver Washington quarters were replaced with cupronickel ones in 1965.

|Philadelphia||1966 SMS quarter||2,261,583|
Interestingly, all quarters minted from 1965 to 1968 didn’t have the mint mark. Besides, the coin composition transition caused a minting delay, so the release of the 1966 Washington quarters only started in August of that year.
During the next five months, this mint produced and released 821,101,500 regular coins without the mint mark. However, there were no proof coins with the 1966 year on the obverse. Instead, you can find collectible coins from the Special Mint Set.
The number of coins minted for this set was 2,261,583 pieces. Each set contained a quarter (Washington), cent (Lincoln), half-dollar (Kennedy), dime (Roosevelt), and nickel (Jefferson) packed in a plastic holder. Since the demand was high, the US Mint limited the order to 25 sets per person.
The crisis that affected the US Mint during a few years of the coin composition transition started to disappear at the beginning of 1967. That year, minting dates finally normalized, so proof coins and pieces with the mint mark were back again in 1968.
Features of the 1966 Quarter
Flanagan did his best to create an elegant coin to honor the first President. Besides, this simple 1966 Washington quarter design contained several symbolic elements describing American goals and striving.
The obverse of the 1966 quarter (Washington)
Looking at the obverse side, you can see Washington’s profile facing left as the dominating element. The date 1966 is under the bust, while LIBERTY is above it.
On the left side of the field is a motto, IN GOOD WE TRUST, positioned in line with the upper part of Washington’s neck. Under its right side, you can see the initials JF for John Flanagan, the coin’s designer.
The reverse of the 1966 quarter (Washington)
The reverse quarter side features the heraldic eagle featuring widely spreading wings and a beam of arrows holding in its claws. The UNITED STATES OF AMERICA frames the coin’s upper edge, while E PLURIBUS UNUM is between the eagle and the country name.
The QUARTER DOLLAR stands along the lower edge of the coin. Between the denomination and an eagle are two olive branches connected in a wreathe.
All these elements have specific symbolic meanings. For instance, the eagle symbolizes the independence and strength of the US. Arrows present the country’s readiness to defend itself, while the olive branches are there as a symbol of peace.

Rare 1966 Washington Quarter Error List
1966 was one of the transitional years for the US Mint. As always, when the coin composition changes, you can expect more errors than usual. The list of the most significant 1966 quarter errors includes:
Doubled die reverse is an error of duplicated design elements on a coin surface. It happens because of the die or hub misalignment during the minting process. The doubling intensity can be from slight, barely noticeable to strikingly extreme.
The coins with easily visible doubling are a popular variety among collectors and are often worth a premium. For instance, one quarter in XF 45 grade with DDR error won an auction record of $920 in 2012.
Quarter struck on a dime planchet
This error happened when the quarter was struck on a dime planchet by accident. Since dimes are smaller than quarters, you can see coins with missing elements. Such an error coin can reach up to $300.
Quarter struck on a nickel planchet
In this case, the 1966 quarter was struck on a nickel planchet. Since nickels are smaller than quarters, such coins come with a partially missing design. However, you can recognize the date and a partially present reverse upper design. These quarters weigh approximately 0.1764 ounces (5 g) and can be worth about $100.
Quarter struck on a five-cent planchet
When the Washington quarter is struck on one cent planchet, the result is a coin without some design parts. For instance, you can see a specimen without the words LIBERTY and QUARTER on the reverse side. Depending on the missing design, such pieces can cost over $200.
Magnetic wire struck in obverse
This error occurs when a wire strikes through one of the coin’s sides and remains there. You can recognize such a coin by the wire shape, similar to a horseshoe, dominating the obverse.
