As I have previously mentioned, I purchased a 2009 Proof Set due to the price of the set. When I received it in the mail and opened it, I was surprised to find an extra panel with 5 individual Lincoln cents. Of course this led me to investigate why these cents were added into this particular set. As some of you are probably aware, this was the Bicentennial Lincoln Cent year. Lincoln's birth was 200 years earlier and it had been 100 years since the Lincoln cent was minted by the U.S. Mint.
