There was a similar discussion about the 52 Mantle on CU recently. It is a high number but a double print and there are a lot of them so why does it sell for so much in any condition.
Admittedly with the Mantle there are other factors, but when cards like that and the Pafko keep coming up, and keep selling for a premium, it is what it is, a market result. Maybe the market is irrational and if one waits long enough it will straighten out.
