Lincoln Cent

From 1909 to 1958 the reverse featured two sheaves of wheat. In 2009, the Mint issued four different pennies throughout the year as part of the Lincoln Bicentennial One Cent Program. In 1943, pennies were made of zinc-coated steel because copper was needed during World War II. At the beginning of 1943, however, a limited number of copper pennies were struck by mistake. In honor of the Mint’s 225th anniversary in 2017, pennies made in Philadelphia had a “P” mint mark for the first time. In 2019, the West Point Mint made special collectible pennies with a “W” mint mark.
