A PSA 2 Mickey Mantle rookie just sold on ebay for 35k.
That card cost $500 in 1987.
Jordan and Gretzky are the next Mickey Mantle.
10-20 years from now those Jordan's and Gretzky's that people sold for
great profits today will only be paying much higher to get those cards back
if they want them.
The best thing to do if you're selling your PSA 8's or PSA 9's today, is to
take a little bit of that money and buy a PSA 5 with the profits.
Mickey Mantle 1952 topps has 74 PSA 7's. 35 PSA 8's and 6 PSA 9's.
Gretzky 1979 opc has 1093 PSA 7's. 742 PSA 8's and 89 PSA 9's.
If you believe that there are 15-20 Gretzky collectors for every 1 Mantle collector, then you feel that Gretzky cards will rise like Mantle.
If you feel that the 15-20 to 1 ratio is not even close, then you may feel the Gretzky craze we are in is overdone.
