Starting in 1916, following the Barber Series, came the Standing Liberty Quarters with the designers initial (M) placed on the obverse. The most popular and distinct attribute of the Type 1 (which lasted from 1916-1917) was Libertys exposed breast. This was changed (covered with armor) just a year later as many Americans found it quite offensive at the time. Another diagnostic of the type is the lack of three stars depicted below the Eagle on the reverse. All mintmarks are located on the obverse. This type also possesses the famous and rare 1916 Standing Liberty Quarter.
