I was wondering if I could have some opinions on this nickel. The color and toning are even all over. No dark, or rusty spot's. No places that looked messed with to make it a magician coin. It weighs 4.68. it does look like maybe it has some clashing? Not that it would cause it. But why is this nickel magnetic? It sticks to a magnet, all over, and on both sides. Thanks for reading, I appreciate any help!
