NM98 was a 6-8$ book into its first few years mainly because of Domino speculation
That died quickly. The book then settled into being part of the run, but was tougher to find than the surrounding issues, as many collectors snapped it up if they saw it in the bins. I used to find them for $3-$5 regularly in the 90s, but many were the times it was issues 96,97,99,100 in the bin.
THIS. No one really cared for it until the Deadpool hype begun much much later.. But those who wanted copies couldnt find them easily. I actually remember getting stiffed by Chuck on a couple of copies I ordered. I didnt make much of it and just carried on
