Roosevelt Dime

Soon after the death of President Franklin D. Roosevelt in April 1945, legislation was introduced by Virginia Congressman Ralph H. Daughton that called for the replacement of the Mercury dime with one bearing Roosevelt's image. 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 and to aid victims of the disease and their families. The public had been urged to send in a dime to the Foundation, and by Roosevelt's death, the Foundation was already popularly known as the "March of Dimes." Due to the limited amount of time available to design the new coin, the Roosevelt dime was the first regular-issue U.S. coin designed by a Mint employee in more than 40 years. -Wikipedia
