Vickilynn what you have there is a rare error coin . As you may or may not know all coins are printed with the heads upsidedown from the tails side. You can see the upsidedown side comming through the heads side I would say If you go to e-bay and uder coins in the query box put error penny , you may see a few more examples of this . However do not sell that penny until you get about five or six offers or take it to a coin dealer if not several . I can tell you it is rare I have been collecting penny's all of my life those are few and far between . I would estimate it at over 100 dollars and coud bring as high as 200. Do not clean it as it has great value just the way it is put it in a coin sleave and try not to get finger prints on it . good luck and let us know . that is a rare and awesome find. Rob
