Esp. on early stuff like an 1806 quarter ? Good-Fine-EF, then several grades of mint state. Put in VG and VF, reduce number of mintstate prices, not a whole lot of ms-62's around, most are going to be VF or lower,so give prices for real coins that actually trade, not fantasy stuff with pops of 5, if they even exist at all.
Doug: They mainly concentrate on 'investor' coins. They (PCGS) also concentrate on their slabs, and are way overvalued. That is why I never use them. Altho, I would like to sell some stuff at their prices.
Well if you keep that 1/2 value factor in mind I do not think there is even a close second place for such a comprehensive quick reference. They seem to pretty well be able to back up their values if one would search the Heritage archives deep enough.
I subscribe but they are pricey for the subscription if you elect to get the top grades & dealer pricing.

Why doesn't anyone in the U.S. & Canada stick to the good old-fashioned 7 point grading system? To me,if you stick with that,then you won't go far wrong.We don't believe in having several grades of Unc..To me,it is either Unc.,or it isn't.You can't have it both ways. Numbers are too confusing. Aidan.
... AND TO US aMERICANS/cANADIENS ... YOUR SYSTEM IS TOO GENERIC ... YOU CANT HAVE A COIN THAT IS GRADED xf AND CLEAN, AND A COIN GRADED xf AND DIRTY ... A LITTLE FURTHER BREAK DOWN IS NEEDED... LIKE YOU SAID.. YOU CAN HAVE IT BOTH WAYS Sorry .. Caps lock ....
MS? Come on,give us a break! We grade our coins very strictly,but there are some slight differences of opinion in the British Commonwealth grading system.Yes,we classify Proof-like & Proof as being grades,even though,strictly speaking they're methods of production as opposed to actual grades. Aidan.
