The major auction houses and slabbing companies should be playing a part here. Each time they reject a coin as fake, pictures should be stored in their online archives clearly labelled and searchable as such. What are the legalities about owning a fake or submitting it. Could the TPG before returning it take a metal punch and stamp a great big F in the middle of it. There's nothing illegal about owning a fake, and of course there's nothing illegal about sending a fake to a TPG. However, as TPGs' reputation rests on their 'authentication', you would think they have, or should have, an up to date archive of all known forgeries. And if they do have, it should be made available to everyone. Perhaps, like the BNTA, they have a misguided vested interest in keeping the information to themselves
