I have a 1989 penny that has 2 tails stamped on it. The tail on the back of the penny looks totally normal. But the tail on the head of the penny is stamped on backwards and isn't centered. You can see the head of the penny at a certain angle and that's how I saw that it is a 1989. Any idea on this penny? Worth anything ?
It is either a hammer job or a squeeze job where the reverse of another cent was hammered or squeezed into the obverse of your coin. (That is why everything is reversed.) Sorry but it is a damaged coin only worth 1 cent.
Rascal... do you really think a photo is necessary in this case? I believe Hobo explained this well enough, sans photo.
Now that's pretty darn good for you folks to be able to know what someone has without even seeing a photo of it. I can't believe that some of have never heard of or seen a coin that has die brockage. it appears that a hammer job or squeeze job is all that is on a few folks brain if they have one. check out this link and maybe you can see something that may help you learn , notice I said MAYBE and I seriously doubt it. http://www.coinsgb.com/Error_Coins/Brockage.html
A brockage can occur off centered as well as centered . here part of the reverse can be seen on the obv. oops maybe another hammer job LOL.
Rascal is right that you can have an off-center brockage, but an off-center brockage on a previously struck coin that doesn't show some kind of damage or error on the other side would be a little hard to believe. About the only way I could see something like that happening would be for the coin to be struck normally, not ejected from the collar, then a second previously struck coin overlaps the struck coin in the collar and the coin is struck again. Rascal, do you have an image of the other side of that piece?
Conder what you said here is true. This is why I told the op that we needed a photo to be sure what they have. I know how it is when we first start learning about coins , someone just starting out don't know how to describe what they have. I don't have a photo of the reverse side of the coin photo I put on here , it does have a flared out rim opposite the brockage area where some metal got pushed out of the collar. I'm adding a link for a nice ebay coin and it is possible this may be what the OP has then again we have no way of knowing without a photo. http://www.ebay.com/itm/Error-No-date-Full-Mirror-Brockage-Cent-Uncirculated-/330707626326?pt=Coins_US_Individual&hash=item4cffb5e956
