GPA shows prices realized for sales that they have recorded. Currently, no ComicLink sales are reported to GPA and GPA also lacks retail sales from many other sources. Therefore, their numbers are incomplete, and collectors preaching them as gospel is inaccurate and misleading. One high profile example of is the sale of Hulk #1 CGC 9.0 with white pages which sold in a recent Mastro auction for $33,378 and was reported to GPA. In March 2005, a Hulk #1 in 9.0 with off-white to white pages (I think it is the same book before the page quality upgrade) was sold by a consignor on ComicLink for $50,000. So, what is it worth? Taking the GPA number only, a collector would conclude that it is only worth $33K. Taking the ComicLink number only, a collector would conclude that it is worth $50K. Knowing what it sold for in both places, a reasonable conclusion is that what it is worth depends on who is looking for the book at the time, the client base of the selling venue, the scarcity of the book, and what the buyer (and underbidder) is willing to spend to obtain it. If you are a seller, what the book is worth will also have to take into account, keeping in mind the above factors as well, the total commissions (buyer + seller) of the selling venue. What the seller nets = what the buyer ultimately pays for the item minus the sum of the buyer and seller commissions retained by the selling venue.
There are countless examples of items selling on ComicLink for higher than the average GPA numbers (the vast majority of which are comprised of eBay and Heritage sales) or even higher than the book just recently sold for in another venue. Of course, there are also examples where a seller is willing to accept less than GPA numbers for a quick sale (or doesn't know that a book can sell for more than their list price) and the astute buyer can obtain a relative "bargain." Alternatively, an uninformed or greedy seller on ComicLink or anywhere else may overprice a book that is not scarce and it is therefore a pitfall for any buyer that is going to resell in the short-term.
