Now to let you all know first off, I am NOT submitting any coins to PCI but I may be at an auction that has several coins graded by what I believe is the older PCI grading service. My question is for those of you in the know, how do you think their grading compares across the board to NGC or PCGS? What I mean is if a PCI coin is graded say MS 66, do you think it would grade the same, one grade less or way low if unslabbed and sent to NGC or PCGS? I want to have an idea what to price coins I may bid on so I don't overbid just cause PCI's grading might be high. Of course I will try to look at as many coins as possible before the auction to see how good they really look but it appears preview time will be limited and there are a lot of coins.
