Sadly, I don't think this is an error coin. Now, I know what your thinking: "What do you mean it's not an error?! It's got the image of another coin on it!", but I'll explain why. Do you see those indents? Like the second date, or the memorial? That leads me to believe that somebody put some glue on, and pressed another coin onto it. If it was a double strike, they would NOT be indents in the coin, they would be "sticking up" from the coin like the rest of the surface. I believe they call that a "vise job"? As for the rim, it might be an error, but I think somebody just introduced it to a hammer. It's too bad you bought this. Just a regular cent that somebody modified.
