Since 1959 (the sesquicentennial of Lincoln's birth), the reverse has featured the Lincoln Memorial. The coin is 0.75 inch (19.05 mm) in diameter and 0.061 inch (1.55 mm) in thickness.
The one-cent coin is often called a penny, but the U.S. Mint's official name for this coin is cent.
History of composition
- Further information: Lincoln cent
- Further information: 1943 steel cent
In 1943, at the peak of World War II, cents of zinc-coated steel were made for a short time due to war demands for copper. A few copper cents from 1943 were produced from the 1942 planchets remaining in the bins. Similarly, some 1944 steel cents have been confirmed. From 1944 through 1946, salvaged ammunition shells made their way into the minting process, and it was not uncommon to see coins featuring streaks of brass or having a considerably darker finish than other issues.
During the early 1970s, the price of copper rose to a point where the cent almost contained more than one cent's worth of copper. This led the Mint to test alternate metals, including aluminum and bronze-clad steel. Aluminum was chosen, and over 1.5 million of these cents were struck and ready for public release before ultimately being rejected. The proposed aluminum cents were rejected due to two factors. Vending machine owners complained the coins would cause mechanical problems. Pediatricians and pediatric radiologists pointed out the radiodensity of the metal inside the respiratory and gastrointestinal tracts was close to that of soft tissue and therefore would be difficult to detect in a roentgenogram. About a dozen aluminum cents are believed to still be in the hands of collectors, although they are now considered illegal, and are subject to seizure by the Secret Service. One aluminum cent was donated to the Smithsonian Institution.
The cent's composition was changed in 1982 because the value of the copper in the coin started to rise above one cent. Some 1982 cents use the 97.5% zinc composition, while others used the 95% copper composition. The price of copper later returned to profitable levels.
