Isn't it really as simple as finding out who submitted them for grading and who consigned them to the various auctions? If it's one and the same, seems pretty open and shut case. If not, perhaps a middle man or a private sale in between(which I doubt).
Seems like a couple of phone calls to the various entities would provide the answers.
