Like a lot of collectors, I check all mine whenever I find them. I used to find nothing but non-magnetic at first -- I guess I had a straight run of about 50 or 60 with nothing but non-mag, and so I thought that the magnetic must be the tough ones to get. But then I starting finding the magnetics too, and now I've got a whack of those. I'd say 50/50 is about right.
