My guess is non-ferrous, Tin, which wouldn't be affected by a magnet, Kerris L Ravenhill -
@kerrislravenhill But yes, a magnet is a good test, like the best. I always have a small magnet, in my car, for that purpose, but, well, you know me, I didn't think of it. Still doesn't make sense, though, unless it was done by some young, skilled & talented, but dumb kid. Am I allowed to say that? Sorry kid.
