Not really, almost every fake PCGS and fake NGC slab has a legitimate serial number. You would probably run across more database errors where a legitimate serial number isn't listed than you will fake slabs with bad numbers. No the second coin is the real one (or at least the slab on the first one is fake.) How do you "go after" someone who is in another country, and where what they are doing is perfectly legal in that country?
Absolutely right. Only way to have any certainty as to the genuineness of coins, especially like that one that is so often counterfeit.
I own 9 trade dollars at present 7 are slabbed and all came from reputable sources the other 2 are rW and came from local New England estates where I could examine them in person I have zero problem with any but this Is one coin I would never buy slabbed or raw from someone I didn't trust or have done business with before the fakes are that scary good more so than any other coin
