Didn't you see my smiley face after my comment
But on certain cards; restoring them to 1-3 is actually an easier gig; for if you're a grading company and the card is like $1K and in bad condition; do you automatically question said card like you would a higher grade example.
And, in the 1980's, we had really good 1953 Topps Mantle fakes running around North Jersey, and the funny thing was those cards would be vg/ex and not better (I think there were some other cards as well). But the reason the fakes worked so well WAS that they were in vg/ex condition and if you were a store owner, would you think that such a card was faked?
