Larry,
They looked good to me, the corners have natural wear and the colors on some don't look quite right but it is probably his scanner settings. All of them have rounded corners and very minimal if any creases, but that really shouldn't raise a red flag either. The one I questioned the most is his J.J. Clarke card:

I'm assuming some 19th century kid decided to use an eraser on it. If so, then it's okay since the kid didn't know any better and that card has always looked funky to me. He has two Clarke (erase variation) cards listed, but I'm assuming

he listed the same card twice. As far as thickness goes, your computer resolution is way better then mine

.
I will add that if those cards are reprints, then we are all in big trouble.
Lovely Day...
