In 1907 a collaboration between the dynamic president Theodore Roosevelt and renown American sculptor Augustus Saint-Gaudens resulted in the replacement of the previous Liberty Head design on the ten dollar gold coin. The new design featured a native American on the obverse, and a standing eagle on the reverse. The Indian was modeled after the figure of Nike (representing Victory) that was part of the Saint-Gauden’s equestrian Sherman Monument located at the entrance to New York’s Central Park, and the reverse was a representation of America’s symbol, the bald eagle.
