ADQ value, while never that great, is pretty easily divided with a visual clue: the early issues were
digest-sized, had a higher quality of article (generally speaking), and tend to fetch a higher price; the later issues were
magazine-sized, had goofier articles (the whole system was goofy by that point), and usually fetch lower prices.
