TPG anacs, ngc, pcgs

Can someone here tell me what the differance is with these three TPG services and would a lets say a anacs proof 68 cross at the same grade in a NGC or PCGS holder

Possibly, sometimes. Most likely, no... most of the time. The grading standards, between TPG's are not standardized - as are most measures used in commerce and science. Because of this lack of standardization, there are variances between TPG's - and often within one service as well. You must adjust to the fact that a grade by a TPG is an opinion - albeit usually a reliable opinion. Opinions vary and are not supportable by hard standards (i.e. the National Bureau of Standards). All that being said, your original question, if it is to be answered utilizing the accepted dogma.. is that the more consistant (and some say stringent) standards (opinions) are to be garnered from PCGS and NGC. The confidence level goes down from there as you plumb the bowl of alphabet soup (TPG's). I hope that helps somewhat. Cheers, RickO

Well said. I would state flatly that there are no guarantees. Grades among these parties should remain similar, but again, it's opinion and opinion varies.

So PR68 anacs may only be a 66 or 67 in ngc and a 65 or 64 in a pcgs holder. But very unlikely to cross at the same grade. Thanks for the information. Bill

No, you should never see that extreme of a variance on a proof coin

Not neccesarily that big of a drop, or even any drop. Do you have a picture of the actual coin in question?
Some of these guys can tell you what you need to know, in my experience they are VERY accurate. Also great at spotting problems.

Let me add a caution... sometimes... a coin from a lower rated (by opinion - again) TPG will cross at the higher tier, or even upgrade. So it is no guarantee that the grade will sublimate. The best advice is for you personally to learn grading skills.. then you can attribute your own coins and utilize a TPG at your discretion. Cheers, RickO

No i don't have it yet should get it later today will try to post pics later.Bill

they all have different standards. it's impossible to 100% accurately predict whether 1 will grade something the same as the other.

My experience is that ANACS is really tight on proofs and copper. If you search eBay for Pf70 grades from these 3 grading companies, you will find many more examples of PCGS and NGC than you will ANACS. Is ANACS tighter or do they just get fewer nice coins to grade? I can't speak for what others have seen, but I've sent ANACS several nice proofs and only managed to get one graded as high as PF69.

I have been trying to use the guide lines from the red book .I think once i have the coin in hand i can adjust my opinon. Any good grading books I should look for.
