In 1908, the quarter eagle design was changed to feature the portrait of an American Indian, which was the first real native American ever shown on a coin. The same Indian design was used for the half eagle as well.
The new design, by Boston sculptor Bela Lyon Pratt, a student of Augustus Saint-Gaudens, represented an innovation in American coinage. The designs were incuse or inset in the surface. This was a first in US coins.
