We found this penny in our change today and are trying to get some information on it.
Here are the pictures:

The "tails" side of the penny is a very nicely struck normal image. The "heads" side, however, is concave and carries two images: The most obvious image is an enlarged, reversed (mirror) Memorial and "E Pluribus Unum". Very faintly, however, you can also see the outline of the Lincoln head which should be there instead. No date is visible. Based on my own metal-working experience, I'm convinced by virtue of inspecting the integrity of the coin and the metal that this is not a post-mint error or a "manufactured fake". But, having little numismatic experience, I do not know exactly what it is or what caused it. Is this what is known as a "brockage strike"???
Any information greatly appreciated. Thanks!!!
