Mercury Dime history

The Mercury dime was introduced in 1916 as part of a major artistic redesign of U.S. silver coinage. Adolph A. Weinman’s obverse actually depicts Liberty wearing a winged cap, symbolizing freedom of thought, but the portrait was soon nicknamed “Mercury” because of its resemblance to the Roman god. The reverse shows a fasces and olive branch, combining strength with a desire for peace. The series continued through 1945 and was replaced by the Roosevelt dime in 1946.
