The early part of the 20th century was a time of great creativity in the design of U.S. coinage. August Saint-Gaudens’ double eagle was introduced in 1907, along with his Indian Head eagle. Victor D. Brenner’s Lincoln cent, commemorating in 1909 the centennial of the President’s birth, broke new ground- it was the first use of a presidential portrait on a circulating coin. A few years later, in 1913, James Earl Fraser’s Indian Head, or Buffalo, nickel was introduced, followed shortly thereafter in 1916 by Adolf A. Weinman’s Winged Liberty Head (Mercury) dime and Liberty Walking half dollar and Hermon A. MacNeil’s Standing Liberty quarter.
