I think #2 first print has a .60 cover price and 2nd print has .75 (could be wrong......)
I just scored a copy of 155 and it cost me $90 bucks. The average price at Heroes Con was 155. I got lucky on mine. Also if you are putting a vintage run together do not forget about the special issue than came out right after 155. That book goes for 80-175 depending on condition and seller. I got mine for 50 but the tag said 80. Funny thing though, I was going to shell out the 80 but the seller stated 50 before I could say Ill take it. Go figure
