I was looking through a box I had full of comic books and I have Godzilla kind of monsters from 1977 ed 1,2,3,4,5,8,9,10,11,12,13,14,15,16,17,18,19,20,21, 24 I’m wondering if they are rare or something I have them in mint condition they are all in plastic and have cardboard on the backs to keep them straight!
