Well, some of that weight was from gold foil and chromium, no doubt, but those were the usually the "regular", there weren't that many variants (compared to now) back then. few issues had one, they were reserved for special issues, and there was usually only 1, maybe 2, now it is every issue, a 1:10, 1:25, 1:100... Heck, 20 years later some of those variants, the ones with not crazy print runs, are actually worth something! My theory is that if you were a monthly comic buyer back then (A) half buying to read and (B) half buying to collect because you thought things might gain value, which was probably a lot of people, when you walked into a store in 1996/1997 onward and saw dozens or more of long boxes of overstock unsellable drek and all those books of a few years earlier in 4 for $1 or 10 for $1 boxes, you had to seriously re-think Part B of that equation, and if the stories/art were getting worse, Part A was impacted as well. I was a 5 or 6 book a month off the rack guy then, but I basically gave up when it became obvious everything I was paying cover price for was likely to go into the discount box. So off the rack buyers got paired down to the 80-120,000 or so people in the USA who need their new comic fix every week and who are willing to pay extra to get it now and for sure.
