I ordered 31 NM books from Chuck in his recent blowout sale. Most where $1. I checked off 31 books from my want list and filled 31 holes. The books were all 80s and early 90s including Punisher (1987), various Valiant, The Thing, Further Adventures of Indiana Jones, etc.
The results are in... of the 31 NM books...
26 were 9.4 or better (a few possible 9.6s)
4 were 9.2, and
1 was 8.0
In all, a good experience.
