My own take on releasing pics or not is that it really doesn't matter. tb mentioned the "freshness to market" issue. It is true that some books that are repeatedly offered for sale on all the auction sites etc may seem stale and get somewhat depressed prices that way. But this is really not that issue at all. Your books have never been offered anywhere(!!) and releasing pics in my opinion is only going to whet appetites, like ciorac said, for when/if there is a sale. In my opinion, this is really a non-issue in your case and just applies when someone is trying to sell the same book over and over again, which is clearly NOT the case here! If the Mile Highs had never been found, and someone released the pics of the mile high collection tomorrow, does anyone really think that the Mile Highs wouldn't get amazing prices at their inaugural sales because the image release of all those mint books had somehow made them "stale"? Give me a ing break. People would instead be setting aside every dollar for the day those books went on sale. IMO, same thing albeit on a smaller scale here. I think tb was looking out for you, which is cool but I totally disagree in this case. To look at it another way, even if every single scan was released there would still be plenty of questions to keep people interested upon eventual sale. (Does cgc agree they are unrestored? What will the Action 13 grade out at?? Is that the nicest AA16 graded so far? etc. etc. etc. I guarantee you once the books were sent in to cgc, you'd have "round 2" of collector buzz. You'd have folks comparing the page quality and numerical grades to other known pedigrees to see how the collection compares to other pedigrees, etc etc. The fact is that a front and/or back cover scan really doesn't tell a purchaser everything they want to know, and moreover in my opinion the freshness to market issue is only an issue if the books are in the market(!) which they aren't and have never been!!).
Do agree with all those recommending cataloging the collection. I don't think there's any question the collection is worth at least the 1m suggested with adventure 40, AA 16, tec 27, supes 1, and 996 other unrestored GA books!
