Did you pick up on his stated dimensions, Tim?
He's talking about a barcode mark that's only about .004" high by .040"
wide and barely visible. Shure enough, my tired eyes would never find it
without magnification.
I don't think I'd have a problem paying market price for a rare coin
with that kind of mark on it, if it gave me even a tiny bit more chance
to prove it was mine and recover it if it got "grew legs" and later
turned up somewhere.

But it sounds like what he described would be "removable" by someone who
knew it was there.
