The Lincoln cent or Lincoln penny is a cent coin (or penny) (1/100 of a dollar) that has been struck by the United States Mint since 1909. The obverse or heads side was designed by Victor David Brenner, as was the original reverse. The coin has seen several reverse, or tails, designs and now bears one by Lyndall Bass depicting a Union shield.

In 1905, sculptor Augustus Saint-Gaudens was hired by the Mint to redesign the cent and the four gold coins, which did not require congressional approval. Two of Saint-Gaudens's proposed designs for the cent were eventually adapted for the gold pieces, but Saint-Gaudens died in August 1907 before submitting additional designs for the cent. In January 1909, the Mint engaged Brenner to design a cent depicting the late President Abraham Lincoln, 1909 being the centennial year of his birth. Brenner's design was eventually approved, and the new coins were issued to great public interest on August 2, 1909.
