Coin and Paper Money Collecting/error penny


I have an very interesting error penny in my possession, and looking online I think it may be one of a kind.  The reverse is fine, however the front contains a second copy of the reverse side ont top of it at a 90 degree angle.  It is dated 1973. I would like an opinion as to whether this coin may be valuable to a collector. I am attaching a picture for your review.


Based on the attached photo, I'd say you have a normal cent that had glue applied and stuck together with another cent. I do not believe it to be a genuine mint error.There is a high possibility that what you see may be dried glue where another coin came in contact with it prior to drying, transferring the reverse image onto the coin. Altered coins would have no added numismatic value.

Sometimes people try and fool you into thinking you have a real error coin. Here are examples of coins either being altered or damaged.

If you live close to a local shop, they should offer an opinion as to it's value and if it is authentic at no charge. Remember, should you choose to sell your coin, get at least two estimates from professional coin dealers (PNG). I've listed a link for you to find them in your area. Link:

Dealers normally pay between 50% to 60% of retail for items they want.
