I have a theory. All metals including copper and nickel have magnet proprieties, and to activate them you would just need to rub a magnet over it in the same direction over and over that would make all the electrons point in the same direction which would make it magnet, I have never done this on a coin but I have done it on other things. The way to tell is take another magnet and point one end at the coin, if it sticks then flip it over to the other end. One if the ends should push the coin away. If that happens then I can tell you how to make it not a magnet.
