President Franklin Delano Roosevelt's sudden death of a cerebral
hemorrhage on April 12, 1945, compelled Treasury officials to
recommend the late president's portrait to be immediately placed on a
coin of regular issue without having to wait for the centennial of his
birth as had been done with Abraham Lincoln for the cent.
The dime was one of only three circulating coin denominations
available for use for the memorial without introducing special
legislation. The other two were the Lincoln cent and the Walking
Liberty half dollar. The Act of Sept. 26, 1890, permitted the
Secretary of the Treasury to change the designs on circulating coins
after 25 years without the need for congressional approval.

Chief Sculptor-Engraver John R. Sinnock's adopted obverse shows a
portrait of Roosevelt facing left, with LIBERTY along the border
before his face. IN GOD WE TRUST appears below Roosevelt's chin, with
the date to the lower right of the truncation.

design is not much different from Adolph Weinman's design for the
Winged Liberty Head dime, except for the elimination of the fasces in
favor of a torch and making the vegetation more recognizably an olive
branch of peace.
The finished coin was rushed into
production in January 1946 to coincide with the 1946 March of Dimes
birth defects fund-raising campaign. The intimate connection the
Roosevelt dime had with the March of Dimes and the war against polio
is often misjudged by collectors.
Because of the need to
produce dimes in sufficient quantity to be used in the infantile
paralysis drive that year, the first year of issue was also the
highest mintage of the dime struck in silver, with more than 344.1
million coins produced.
The key to the series is the
1949-S, even though more than 13 million were struck at the San
With silver prices rising and
supplies dwindling, Treasury looked at a number of compositional
alternatives to reduce costs. The Coinage Act of July 23, 1965,
resulted in the composition of the dimes and quarter dollars being
changed to two layers of copper-nickel bonded to a core of pure
copper. The half dollar was changed to a reduced silver clad
All 1965-67 coins were struck at the various
Mint production facilities, but none bear Mint marks. The omission of
the Mint marks was a continuation of the Mint's misguided belief that
collectors were responsible for the coin shortages of 1963-65. The
Mint did not want collectors hoarding the new dimes and preventing
their use in circulation.
From 1946 to 1964, the Mint
mark appeared on the reverse, to the lower left of the torch, just
above the E in ONE. Beginning in 1968, the Mint mark was moved to the
obverse, above the date. The P Mint mark for Philadelphia Mint-struck
dimes did not appear on the coin until 1980.
after Sinnock's new dime design appeared in circulation on Jan. 30,
1946 (the anniversary of Roosevelt's birth), rumors were buzzing that
the designer's initials, JS, located at the base of the trunk of the
neck opposite the date, stood for Joseph Stalin, the leader of the
Soviet Union. The rumor indicated the initials were put there because
of a pledge that Roosevelt had made to Stalin when the two leaders met
along with British Prime Minister Winston Churchill at the Yalta
Conference in February 1945. The rumor had no basis in fact. The
initials were to designate the design as the work of John Sinnock.
