The 1966 Roosevelt dimes are a valuable part of a long history of dimes. The US Mint struck the first dime (disme) in 1792, while those with the Roosevelt profile appeared in 1946. Their minting has continued since then.
The structure and content of this coin type have changed over time. Initially, dimes were made of 0.900 silver, but the alloy transformed into 3/4 copper and 1/4 nickel in 1965. Therefore, early coins reach higher prices at the current market, while the 1966 dime value is significantly lower.

History of the 1966 Dime
The 1966 dimes are familiar to US citizens by a Franklin D. Roosevelt head sculpture on their obverse. He was the 32nd President of the USA and a philanthropist, and the US Mint started these coins’ production soon after he died in 1945.
The first dimes went public on January 30, 1946, on the 64th Roosevelt’s birthday date. The idea was to honor the President and great leader who led the country through two harsh periods in its history, the Great Depression and WWII.
His achievements were even more remarkable if you know that he also battled the terrible illness polio. By the end of his life, this honorable man dedicated himself to promoting and improving the welfare of others.
For instance, President Roosevelt established the March of Dimes, a nonprofit organization enhancing mothers’ and babies’ health, in 1938. Besides, he started the National Foundation for Infantile Paralysis, and his contribution to the cause was crucial to raise awareness about polio.

Mercury dimes were the predecessor to Roosevelt dimes, being in circulation from 1916 until 1945. New dimes appeared soon after war-President death, and the man responsible for the design was John R. Sinnock.
His initials JS were struck on these coins’ obverse, under Roosevelt’s head. They caused a famous controversy because these initials resembled Soviet leader Joseph Stalin.
After several attempts and setbacks, Sinnock’s conceptual solution for the new coin was finally accepted. His assistant on this project was Gilroy Roberts, later the chief engraver himself.
Apart from initials, the look of these dimes has remained almost the same until now, with some slight differences. However, their composition changed in 1965 from silver to copper-nickel alloy.
According to the Coinage Act of 1965, clad coins got a so-called sandwich structure. In the middle of the dime was copper, while two outer layers were a mixture of two metals.
Unfortunately, the value of Roosevelt dimes without silver significantly decreased, making them less collectible. Since all Roosevelt dimes minted from 1965 to 1967 came from Philadelphia, you can find those coins only without the mint mark.
Features of the 1966 Dime
The 1966 dimes are coins with copper-nickel composition from the regular strike, but you can also find those intended for collectors. These SMS dimes are always a part of the five-piece set containing:
- Kennedy half-dollar
- Washington quarter
- Roosevelt dime
- Jefferson nickel
- Lincoln cent
The Roosevelt dime’s face value is 10 cents, which is usually the price of these widely used and easily recognizable coins found in circulation.
The obverse of the 1966 dime
Unfortunately, Sinnock had problems with the Commission of Fine Arts before the design was finally approved. There were some technical issues regarding the authenticity and magnitude of Roosevelt’s head on the coin obverse.
As the dime is only 17.9 mm (0.7 inches) in diameter, Roosevelt’s bust looked too small with the engraving LIBERTY placed above his head. So, the designer needed to move the inscription slightly to the left to make President’s profile more visible.
Besides, the bust of Roosevelt facing the left side of the coin looked like he read LIBERTY, the most symbolic American word. By doing so, Sinnock satisfied all criteria of the Committee of Fine Art.
Under President’s chin is the saying, IN GOD WE TRUST, while the designer initials JS are under the bust just next to the minting year, 1966. There are no mint markings, as all the coins minted that year came only from Philadelphia.
The reverse of the 1966 dime
The 1966 Roosevelt dimes have an amazing and symbolically perfect reverse. The torch is in the coin center, with the olive branch on the left and the oak branch on the right side. They represent symbols of peace and strength.
The UNITED STATES OF AMERICA is on the top of the reverse above the torch, following the coin edge. On the other hand, the ONE DIME value of the coin is at the bottom, under the torch and two branches.
There is also a writing E PLURIBUS UNUM in the middle, which looks as if intertwined with the torch and twigs. One of the first ideas was adding a hand holding the torch and branches.
However, that idea was dismissed together with several other solutions the designer had. Finally, the reverse was approved after numerous sketches, changes, and disputes, and coins went to minting.
Interestingly, they became the most common and recognizable pieces in modern American coinage. Believe it or not, you can still find dimes minted in the 1960s circulating across the United States of America and reminding people of great Roosevelt deeds.

1966 Dime Grading

The MS dimes come with different qualities, and a higher number means a better appearance and preservation level. In the case of the 1966 Roosevelt dime, the ranking goes from MS 60 to MS 69.
Rare 1966 Dime Error List
Imperfection makes coins desirable to collectors. Since such pieces are often rare, you can expect them to be more valuable than standard ones. Several variations and errors increase the price of the 1966 Roosevelt dimes.
Full band dime
Besides regular coins with average quality, the 1966 dime set includes Full Band coins that look fabulous with all details visible as planned. In this case, you can notice that all torch lines and bands are distinctive and highly recognizable.
That feature makes these specimens more costly. Most are typically worth $20 to $600, but the rare 1966 MS 68 dimes often reach $2,500. The most valuable piece in MS 68 grade was sold in 2013 at $2,820.
Dimes with a doubled die error have a doubled image or the word LIBERTY. When the imperfection is noticeable, such a coin can be worth up to $600.
During the production process, some dimes ended up with the clipped planchet error, looking like small bites on the coin rim. The 1966 dimes with such a flaw can be worth about $30.
This atypical error can significantly increase the prices of dimes minted in 1966. Due to improper manufacturing, you can see the number 5 on Roosevelt’s face on the obverse. Such specimens are scarce and can cost over $2,000 at auctions.
