Hawkman posted this in another thread:
1,19,27, 33, 48, 53, 61, 63, 92 are the important books/keys right now (61/63 because of chew).
also, i would add that #33 (2nd print) might have less interest than 1st print, but it's probably more valuable than the 1st print.
imho:
#53 relies on abraham staying alive
#61/63 will hold value for now, but after chew stops?
#92 relies on jesus' character. will he stay around and become a prominent character?
Does 61 stay up in lieu of 63 due to the Carl/Ben sequence? It's a turning point for the series.
