i dont own any marvel star wars comics, all mine are dark horse.
crimson series
shadows of the empire
boba fett series
I had the Mara Jade series... but I think those were Dark Horse. :(
As for the other comics, try Google. Thats the best I can tell ya, because I never looked up on comics... :(
how much they cost? or how much they are worth?
a mint comic from marvel goes anywhere from 2-6 dallors maybe, but its really gonna cost different where you buy it, at a comic shop, pretty much whatver your willing to pay, online, 8-9 is common.
if there fairly cheap id buy em.
it also depends how old you want them, i was in a toy shop, they were going from 5-190$ al;l depends what you buy.
