These are all four 2009 Lincoln cents from both Philly and Denver mints each in an attractive Whitman holder which commemorates Lincoln's 200th birthday and the 100th anniversary of the Lincoln penny!  Also included to make it complete are the very first year for the Lincoln penny, a 101 year old 1909 Lincoln Wheat Penny in the Philly cent set holder and the first Lincoln reverse change to the Lincoln Memorial, a 51 year old 1959 Lincoln Memorial penny. Very nice set and a must for any and all coin collectors!
