Line up the nickel, the dime, the quarter, and the penny. Why are the other presidents turning their backs on Abraham Lincoln?
According to the U.S. Mint, The likeness of President Abraham Lincoln on the penny is an adaption of a plaque executed by portraitist and sculptor Victor David Brenner. President Theodore Roosevelt was so impressed with Mr. Brenner's design of a Lincoln plaque that he recommended to the Secretary of the Treasury that the design be placed on a coin to be issued in the Lincoln Centennial Year, 1909.
The direction that Lincoln faces on the cent was not mandated—this was simply the choice of the designer.
