Actually the last real world sale was $410 for one grade below the one we own just a couple of weeks ago on EBay. We have confidence in Comics Price Guide, but they do lag sometimes in particular hot and cold books. But, that is not the reason we chose them.
We want the average person to be able to follow along. Comics Price Guide is open to all and is free. Yes, they do underprice and overprice some issues, but overall, they are excellent.
Now, I completely understand that you guys want GPA or Overstreet or any other edge to make your judgments. But, those cost money. The coin is meant to appeal to everyone, not just hard-core collectors. I think that serious collectors will find this fun too, particularly if they follow the crypto world as well.
But, we want the casual collector or even people who just like the movies but are interested in comics to have fun too. As stated on the website, if we feel that the Comics Price Guide is just way off the mark on a particular comic book, we will change the value to reflect that.
As a 9.6 Avengers Annual #7 just traded recently for $410, we just don't think that Comics Price Guide's value for a 9.8 is that far off. And, of course, auctions and other sales can fluctuate wildly as you guys know. But, we will be on the lookout for any big disparities. Plus, I am sure people will tell us loud and clear!
