98 is certainly in more market favor at the moment (used to be 105)
Been going 800-1000 a point
Actually, 98 has been easing back down. A really nice 6.0 with nice pages didn't even hit 4K in the last Clink auction. While 98 is a desirable book I personally didn't understand the sudden run up last year. Correct me if I am wrong but the origin story, which starts in 98, is a trilogy, consisting of 98,99, and 105. 105 not only concludes the origin but summarizes all three parts. As you stated, for years 105 was the go to book. I love all the issues from this era and they are all exceptionally rare in the census. Obviously the run up in 98 has brought many more to market and is actually got a higher census than the other issues around it.
