The U.S. Mint is changing the design of the penny for the first time in 50 years. In honor of Honest Abe's 200th birthday, there will be four new images on the back of the coin, depicting four different stages of Lincoln's life. The 16th president will remain on the front.
As it turns out, the penny's been at the cutting edge of coin design since Lincoln first appeared on it a hundred years ago.
Host Scott Simon speaks with Robert Wilson Hoge of the American Numismatic Society about how the Lincoln penny was the first U.S. coin to carry the picture of a famous person.
