Found this the other day, and it is the same size as a quarter, and it has a copper colored "side-stripe".
It looks like a knock-out from an electrical panel. Is is magnetic? Does it weigh 5.67 grams (correct weight of a clad quarter)?
I don't have a scale, but I just tried it with a magnet, and it is magnetic, so, not a coin! May be what you said, haha. My bad.
