Step 1 : Introduction to the question "Which U.S. President appears on a dime?"
The current design on the obverse of the dime first appeared in 1946, soon after the death of President Franklin Delano Roosevelt. The Roosevelt dime was released on the late President's birthday which was January 30th of that year. After his death in 1945, citizens began writing to the Treasury Department requesting his likeness be depicted on a coin. The dime was chosen to honor Roosevelt partly due to his efforts in the founding of the National Foundation for Infantile Paralysis (later renamed the March of Dimes), which originally raised money for polio research.
