There are some who can easily peel off the entire front of a T206 card and thereby swap a common back for an uncommon one. Does anybody know what the tell-tale signs of such an alteration would be? For instance, might there be some chemical scent if it had been done recently? I actually have no idea how it's even done, so I'm just fishing for ideas at this point and trying to avoid any obvious pitfalls. Thanks.
