Standing Liberty Quarters (1916-1930)

The type of quarter was designed by Hermon A MacNeil. The left arm of Liberty is upraised, uncovering a shield in the attitude of protection. Her right hand bears the olive branch of peace. MacNeil's initial M is located above and to the right of the date. 

There was a modification to in 1917 to cover Liberty's exposed breast. The reverse has a new arrangement of the stars, and the eagle is higher. In 1925 a depression was made in the pedestal on which Liberty stands and that bears the date. On the earlier issues the dates wore off easily because they were too high and were not protected by other features of the coin. The new "recessed" dates proved more durable as a result of this change.
