If all the owners of the pieces could provide pictures, that would be great. Joining everyone would be expensive, and buying all the coins would be immensely expensive. Both infeasible as far as I can see... If this does exist, I don't see how it can't be discovered putting pictures of all coins, from all angles, side by side.
This is bullshit, not even worth wasting time. The guy is a fraud and he even came with his puppet ukcrypto to say he's a rich and famous artist.
His previous work has sold for millions... but he can't afford to buy a good lathe. He most likely doesn't even own a laser cutter, just sends the designs to someone who does.
He has shown me evidence he is who he says he is. Am I a sock puppet too?
BTW: laser engravers and CNC mills don't leave the wood grain behind when they are used to carve designs:
