It's been nearly five years since these classic-era US commemorative coins have been posted here, so...1920 saw a pair of US commemorative coins: the 1920 Maine Statehood Centennial Half Dollar and the 1920 Landing of the Pilgrims Tercentenary Half Dollar.
The 1920 Maine Statehood Centennial Half Dollar presents the Maine Coat-of-Arms on its obverse and a pine wreath on its reverse. (You can read more about the Coat-of-Arms here:
