2009 marked the 200th anniversary of the birth of our 16th President, Abraham Lincoln, as well as the 100th anniversary of the Lincoln Cent. In honor of these two events, the Mint released four pennies with a different design for each reverse. The first penny of this series was released on Lincolns birthday, starting with the “Log Cabin” design and followed with designs for Lincolns “Formative Years,” “Professional Years,” and “Presidency.”
