I also agree, the scans are of two different cards, not only are the holders different, there is a small chunk missing out of the top right of the front side, but this missing chunk doesnt show up on the reverse. I also think you would see that crease, easily seen on the front on the reverse as well, but you do not.
I did a small search on the phone number and found it is a landline in CLeveland, the guy also has a sportscards wanted ad listed in Fort Lauderdale and Miami newspapers. His email is

20k is probably reasonable for that card, but i would be hugely sceptical
