Thanks for the interest! Here's the whole thread on collecting the run.
As to a few of your specific questions: of the higher graded ones, I believe just the 15 and 39 were bought raw. Lots of the VG-ish ones were raw from ComicConnect, who were usually within a 1 to .5 on grading. I did upgrade a handful along the way, mainly to try to get them all blue label, though obviously the 23 ended up being an exception. Not currently selling the run, but I'm not collecting much anymore either. I did recently got a much nicer 48 from @Point Five, which I'll post when he allows me to.
