The 1966 Quarter: Facts and Figures You Should Be Aware Of

Quarters have a long history that dates back to 1796, the year when these coins were released for the first time. All along its path, their appearance changed from more symbolic (rather metaphoric) designs to realistic, commemorative issues. 1966 represents a transitional period when silver was phased out, and a new era of coin composition began.

Quickly About the Historical Context of Quarters

Since its introduction in 1796, the quarter, officially known as the quarter dollar, has become an integral part of circulating currency in the United States. The first quarters of the series, which reflected the classical artistic influences of the time, were made of silver and had the Draped Bust design (which is considered rare and valuable these days, though it is not the case in the article). 

The composition and design of the quarter changed over time, with significant modifications like the 1916 shift to the Standing Liberty design and further to the 1932 Washington quarter, which was meant to commemorate George Washington's 200th birthday.

The XX century dazzled with modifications, too. The Coinage Act of 1965, which replaced silver in quarters with a copper-nickel-clad composition and removed mint marks, too, reflected the beginning of a new wave in American numismatics and, by 1966, the quarter had completely switched to this more affordable and durable material in the end. This was the result of rising silver prices and post-war economics that suffered from deficiencies in all sectors and increasing demands not to mention.

Design and Composition

Before we define the 1966 quarter value, it is vital to observe the appearance of the coin. To be more precise, this coin retains its recognizable design, with George Washington on the obverse and a heraldic eagle on the reverse with no silver in its composition. Why? Due to the economic realities of that period, the production processes underwent a shift switching to a copper-nickel-clad composition instead of 90% silver and 10% copper). 

The appearance of the coin, however, cannot solely define its price and significance. It may be considered as a part of the price-determining process only when taken into consideration in combination with other factors, such as mintage figures and locations, as well as designations and their state. Here is what we should be aware of when defining the 1966 quarter worth. 

Mintage and Production Figures

The minting process in 1966 was a bit different from what the US Mint was used to before. In order to discourage hoarding, the Mint decided that they would produce quarters without mint marks at all. Here is what we know about mintage figures in 1966.

1. Traditional Circulating Coins

Mintage: 821,101,500 pieces

In an effort to minimize speculation, the Mint did not mark any of the 1966 quarters, even those made at various facilities.

2. Special Mint Sets (SMS)

Mintage: 2,261,583

Along with the circulating coins, there were also released Special Mint Sets (SMS) as an alternative to traditional proof coins. Although these sets were not as fine as the conventional proofs, these were struck by the San Francisco Mint with more care than coins meant for circulation. 

Unlike circulating coins, SMS quarters may have a semi-reflective or matte texture and crisper features as well. Besides, they are also attributed with designations SP, CAM, and DCAM which stand for “Specimen”, "Cameo", and "Deep Cameo" respectively. These reflect the quality and appearance of the coin, with DCAM examples being the most exceptional and highly prized by collectors.

How Much Is a 1966 Quarter Worth?

Is a 1966 quarter worth anything? In general, the quarter 1966 value is determined by its condition, type, and designations. Uncirculated coins, Special Mint Set (SMS) copies, and coins with possible errors (uncommon and aesthetically appealing in particular) can fetch much higher prices than the majority of 1966 quarters in circulation, which are worth their face value of 25 cents only.

General Value Range

• Circulated Coins: Face value ($0.25) to $0.50.

• Uncirculated Coins: $1 to $10+ for standard coins in Mint State (MS) grades.

• Special Mint Set (SMS) Coins: $3 to $50+, depending on quality and designations.
