If they were found in his friends' grandparents home is he selling them for his friend? Why is his friend not selling them since it sounds like he does not know the card market that well?
Also you stated his story does not have too many holes. I like my stories to not have any holes.
Hope it works out but if you have ever seen the film House of Games from the late 80s how a conman earns the trust of his victims before he swindles them, it would give you pause. Might be worth a trip to Montana.
