I don't have a lot of valuable comics. Nothing that I know of worth more than around $10. As for treasured, though, let's see: Superman Annual #1 (Silver Age) - Would be worth a couple hundred if not in "beat to crap" condition. Superman For All Seasons (hardcover) - Easily my favourite Superman story and since he's my favourite character, well... Post Crisis Superman run... complete run from John Byrne's Man of Steel up through Zero Hour, then a bunch afterwards, trying to slowly complete the run. Green Lantern - complete run of John's/Tomasi's entire era. Sinestro Corps war got me into reading non-TF comics for the first time in well over a decade, love the whole run!
