Barber/Liberty Head Silver Quarters
1892-1916
The Barber Quarter (also referred to as the Liberty Head Quarter) began minting in 1892. Designed by Charles E. Barber, the obverse features a bust of Liberty, similar in style to the Morgan Silver Dollar, wearing a liberty cap with a laurel wreath, and a ribbon that ties her hair at the back of her neck. The words “In God We Trust” appear above her head, with the date found below. Six stars on the left and seven stars on the right represent the original thirteen colonies. The designer’s initial “B” can be found at the base of Liberty’s neck.
The reverse imitates the Great Seal of the United States and depicts an eagle with outstretched wings, holding an olive branch with thirteen leaves in its right claw and a bundle of thirteen arrows in its left. There is a ribbon with the motto “E Pluribus Unum” (Out of Many, One) being held in the eagle’s beak and thirteen stars in the field.
