This is the same for pre-war cards too. You have to look at the sellers other auctions, their history, the cards etc.... If they are not card-sellers then it's understandable. If they are selling other graded cards and these high end raw ones aren't, then there could be other issues to watch out for. Many times it's just an educated gamble. I do it quite often and sometimes do well and others times I don't.
