I found a penny at work that is half silver / half copper. It has a very definitive line across both sides, almost as if it was dipped in something, that separates the silver from the copper. It is a 1978 penny, and has some scratches on the face side. Everything else about it looks normal, and the silver part does not wipe / scratch off to reveal copper underneath. It is as if it is actually made of silver. I‘m just wondering if anyone has any idea what this penny could be / how it can be half silver and half copper. If it‘s nothing I guess I‘ll just add it back into my change bucket and get my 1 cent for it!
