also I do not see any other of those cards graded. If you do, join the John Elway Master Set under football and submit it for set addition.
If it gets added, you may be able to increase the value substantially of the card.
There are only 10 people in this set, but you never know.
$100 is your value. So if you dont mind one of them stealing/destroying your card for $100 then you will be fine. I dont think anyone at PSA would do so, but if it happens you get $100.
