The Lincoln Head Cent is approaching it's 100th birthday and as such, it is the longest running coin in continuous production in United States History. From 1909 until 1959 the reverse bore an impression of two sheaves of wheat, from which originated the term "Wheaties". From 1959 until present the Lincoln Head Cent reverse bears and engraving of the Lincoln Memorial, so they are called "Memorial Cents". From their inception until 1942 the coins were composed of a bronze alloy, 95% copper and 5% tin and zinc. During the War year 1943 the coins were composed of zinc coated steel. From 1946 the composition changed to brass, 95% copper and 5% zinc. After the War, the composition changed back to the pre-war alloy until 1962. From 1962 until 1982 the composition was brass again. From 1982 until present the coins have a 97.5% zinc core and are plated with copper. © 2012THC Toys, Hobbies and Crafts Back to Coin Collecting
