From the 1830s to the 1890s the seated liberty design was practically the only design used for silver coins. A new design was desperately needed so the government offered a cash prize for the best design. Charles Barber made a very robust yet sturdy design that the government found promising. It replaced the previous design on three of the four silver coins.
