The Peace Dollar series was introduced in 1921 to mark the restoration of peace following the end of World War I. The new dollar coin replaced the Morgan Dollar, which minted in 1921 for the last time. The Peace Dollar was designed by Anthony De Francisci and features a crowned image of Liberty on the obverse and an Eagle on the reverse. The Peace Dollar was minted at the Philadelphia, Denver, and San Francisco Mints. It was the final silver dollar coin produced in the United States for circulation.
