The price in for PCGS certified coins
PCGS price guide reflect PCGS certified coins. Some dealers sell MS69 eagles graded by them or some other company (NNC, PCI CCGS etc..) but if you resubmit them to PCGS they might come back as 67 or 68. So there is the price difference. And I am sure if somebody buying certified silver egale they do not pay exact the price but usualy less.
