I don't know what anyone else's point was, but my response to your surprise that the book had more 9.8s than other grades was simply that it likely got that way due to pre-screens because most folks would not knowingly slab that book if they thought it was a likely 9.2, at least not until very recently, and that it would have been financially illogical to do so, at least until very recently. Pre-screens are going to jack up the number of 9.8s vs. 9.6 and 9.4 because it is quite likely many books wind up staying raw rather than becoming slabbed 9.6 or 9.4 (and maybe less so right now as more and more 9.6 and 9.4 are worth it at current prices, but were not a year ago). Really, that's it. Iron Man 150 is not "more common" in 9.8 grade than 9.6 or 9.4, just like Spawn 1 is not more common in 9.8 condition or any number of the MANY books where 9.8s outnumber 9.6, etc., it is just that more people were willing to pay cgc fees to get back a label that says 9.8 and the way many do that is through a pre-screen.
