The 2009 Lincoln Bicentennial coins are special penny designs issued by the U.S. Mint to celebrate Abraham Lincoln's 200th birthday. These coins feature Lincoln on the obverse and four different designs on the reverse representing important phases of his life. They are made of the same material as regular pennies, which is primarily copper with a small amount of zinc.

    These commemorative coins were minted in the standard composition of copper-plated zinc, which is widely used for circulating coins due to its durability and cost-effectiveness.

    These sets contained coins that were struck in a unique copper alloy, which differed significantly from the standard composition used for circulating coins.

    The special alloy used for the Proof and Uncirculated Coin Sets was comprised of 95% copper, making it richer in copper content than the standard composition.
