Lincoln's portrait had been on the cent for fifty years when the Treasury changed the other side. The White House announced the new reverse in December 1958, and the coins went out on Lincoln's 150th birthday, February 12, 1959. Frank Gasparro won an internal Mint contest with his view of the Lincoln Memorial in Washington. Victor David Brenner's 1909 portrait stayed on the obverse. The design it replaced, and the cent's earlier history, are covered on the Lincoln Wheat cent page.
The first change came almost at once. Early 1960 dies used a small date, and the Mint found that the center of the 0 tended to break and fill, so it cut a new master with larger figures. Collectors noticed, and sealed bags of 1960 Small Date cents changed hands for many times face value until the fad collapsed in 1964.
In 1962 the alloy changed quietly: an Act of September 5, 1962 let the Mint drop tin, and the cent became brass. Then came the coin shortage. Mint Director Eva Adams blamed collectors in part, so cents dated 1965, 1966 and 1967 carry no mint mark, though Philadelphia, Denver and San Francisco all struck them. There were no proofs in those years; the Mint sold Special Mint Sets instead. Mint marks and San Francisco proofs returned in 1968.
Copper prices drove the next two changes. In 1973 the Mint struck more than a million and a half aluminum cents dated 1974 and tested bronze-clad steel, but the plan died in Congress, opposed by vending machine makers and by doctors who warned that aluminum would not show on an X-ray if a child swallowed one. When copper climbed again, the Mint switched to copper-plated zinc. Philadelphia struck the first zinc cents on January 7, 1982, and Denver followed on October 21, so 1982 cents come in both metals.
The Presidential $1 Coin Act of 2005 required four new reverses for Lincoln's bicentennial, which ended the Memorial design after 2008. Its successors are the 2009 Bicentennial cents and the Union Shield cent.
