In 1904, President Theodore Roosevelt started to push for improvements to U.S. coins, and arranged for the Mint to engage Saint-Gaudens to redesign coins which could be changed under the 1890 act. Before his death in 1907, the sculptor provided designs for the double eagle and eagle, though the double eagle required adjustment by Barber to lower the relief before it could be released as a circulating coin. Redesign of the smaller gold pieces, Lincoln cent, and Buffalo nickel followed between 1908 and 1913. By then, the dime, quarter, and half dollar were the only coins being struck which had not received a redesign in the 20th century. As the 1916 date approached when the Barber coins could be changed without an act of Congress, calls for a new design increased.
