Roosevelt Dimes of the United States

The Roosevelt dime was designed by Chief Engraver John R Sinnock and has been minted since 1945. The dime was chosen as a tribute to President Franklin D. Roosevelt for his founding of the National Foundation for Infantile Paralysis, which was later renamed the March of Dimes. There was a conspiracy theory going around at the time that the designer’s intials JS, which could be found on the coin, really stood for Joseph Stalin. But the obverse portrait of Roosevelt has stood the test of time and still remains on the United States dime.
