Anyone who does a close study of the actual coins can see this with their own eyes.

And I mean a study of just the coins graded by PCGS. Go through a few hundred of any modern you choose with all of them graded as 69 by PCGS. Have a couple of 70's for comparison. You'll find at least 25%, maybe 50% of the 69's that can't be distinguished from the 70's. You can do the same thing with just about any grade you choose, but to a lesser degree. That is what is meant by consistency.

Do the same study with a group of coins graded by NGC - you'll get an entirely different result. They actually are consistent.

so your contention is that it is not a result of extra strictness that a coin is less likely to be graded 70 at PCGS, but it is a result of random luck, where equal coins are sometimes given their appropriate grade (70), but most times they are not. I suppose that advantage to this is that it increases the public's (those who cannot grade for themselves) perception that pcgs is more strict, when in fact that isn't the case, but it does serve to inflate the prices of PCGS graded 70 coins.

hmmm, I'd never considered that...


Ed, assuming I've accurately summed up Doug's position, what do you think of that?
