The Heritage Auctions site lists current certified populations figures for NGC and PCGS coins. But does anyone compile a list of the certified population figure increases, year by year? This would be very useful for those trying to figure out whether they are buying coins with too much of a premium relative to population figure. Thanks for anyone knowledgeable on this. Useful examples would be MS64 and above type gold, $2 1/2 Liberties to $20 Saints; population figures have no doubt increased greatly during the last 10 to 20 years, but by how much--doubling or four fold?
Heritage no longer lists the pops for PCGS. I first noticed it a few weeks ago. They still give you the NGC pops though. I have pop figures for a few things from some years back, but not everything. And not for every year, just at certain points.
I noticed them doing it for some PCGS coins, but others as you say are unpublished. So you could get PCGS' pop figures directly through their site, but could you reference them without violating the copyright?
Only if they get the labels back on resubmits. On crossovers, they sometimes send the label back to you.
No that far off except for the really rare coins where they don't return the label. If you were talking about a rare gold coin like a CC, "D", "C" mint marked coin it may be different than a common gold coin. The numbers of generic coins out of Europe dwarf other factors.
????????????????????????????????????????????????????????????????????????????? Your posts make no sense. Take a nap.
There's a story in the book Modern Commemorative Coins by Eric Jordan about the "crack out game" (page 81), where "100 attractive W mint marked moderns purchased from the US Mint in a single issue packaging were sent to NGC and PCGS...in small lots". After four re-submissions of those grading less than MS70, the number of MS70's grew from 71 coins initially to 91 for NGC (out of 168 total submissions), and from 28 to 74 for PCGS (out of 291 total submissions). If this story is true, I think it implies that population reports, and grading services in general (at least for modern commemoratives), are pretty worthless...buy the coin, not the holder!
There is a big difference between tiny grade gaps as 69/70 and details grading and numerically graded coins. The TPGSs provide an invaluable service, but probably with the Moderns there are 10X too many of those submitted looking for 70s! And that is slowing down the grading process big time. They aren't going to turn their noses up on submissions. I have never seen where the TPGSs refuse to grade a coin and take the $$$.
Grading has a vital role in quality control in the coin industry. I see even the usual heavy advertisers in Coin World who used to offer unbelievable deals on uncertified coins have greatly increased their offerings of graded material. Possibly CW was getting too many complaints from customers who wised-up to their racket.
There was a study done and the results published in Coin World some years ago where the conclusion was that pop figures can reasonably be expected to be off by about 20%.
I think that population accuracy would vary wildly depending on the series, and on the grade. I'm guessing the top population numbers are quite accurate.
