Here's another catalog, this one from Maxwell Seeley (expired Mar 31, 1981). ASM #1 ($300) was more expensive than AF15 ($275), IH 181 was $10. I did buy X-Men #94 for $75 (not from this catalog) but that was about all I could afford back then. I didn't realize at the time, though, that these prices are only for good, collectible condition (pre-1978). For fine condition, you need to double the price. It's mentioned in the 4th and 5th paragraph on pg. 1 (which I never saw until recently). Not exactly sure what his "good" and "fine" grades would correspond to on our current grading scale, though - maybe Fine and VF/NM?
