How do they come up w/ their numbers?
Do they go to outside experts?
Do they use pop reports?

How do they come up w/ the weighting system???

    They base their weights on medium uncirculated grade scarcity - say MS63 or 64 for older coins and a bit higher for that modern junk. They will take input from outside sources and I'm sure pop reports are a factor in the weighting.

    I think thats pretty crappy. I think condition rarity should be rewarded in some cases....
    And using the pops is useless. According to the pops my 1845-O is rarer that ALL the carson cities...

    Sean,

    They are throwing the populations out the windows in many cases, especially with moderns, because they do not believe that the modern pops are fleshed out enough to get a feel for rarity.

    My understanding of the intent of the system was for PCGS to take a series and then try to weight it using readily attainable grades. In some cases, this does not put a premium on ultra-high grade pieces if the date is normally common. Example, in Washington quarters, a MS-68 piece can run $10K. The 1956 piece has a population of 535 in MS-66, 81 in MS-67, and a single MS-68 piece. Because the coin is easily attainable in MS-66 & 67, the date has a weight of 1. The 1932-D has a weight of 10 (single MS-66 example). This disparity causes the MS-68 in this date to have the same impact as a low grade circulated key date, cost around $100.

    Actually, that MS68 probably has 1/5 the impact of a low grade circulated key date. This is the largest flaw in the system. Unless, of course, they start listing Eliasberg had a bunch of cameo MS Washington quarters???? image

    TDN,

    Don't think that Eliasberg had any Cameo MS Washingtons. The only ones they designate are the 1965-1967's unless they are proofs. But apparantly, it is always a possibility. The "Eliasberg exception." image

    Well, I didn't think Eliasberg had more than one or two cameo proof trade dollars, and now in PCGS's infinite wisdom he had 13 of them! image

    TDN,

    There's a guy on E-Bay who sells proof coins with "lost cameo." Coins he thought that PCGS didn't do him right on and should have got the designation. If you ever sell those Trade Dollars, be sure and call them "lost cameo" and explain that somehow, PCGS considered them Cameo when they registered them for Eliasberg but not for you. image
