An FN/VF copy of Marvel Preview #7 with the first appearance of Rocket Raccoon went for $8.50 a couple of months ago.
But that was before the announcement of a Guardians Of The Galaxy movie that may well co-star the jet set critter, as well as his return in the Guardians Of The Galaxy comic as part of Marvel NOW!
It's not the only comic being affacted, Marvel Super Heroes #18 featuring the first Guardians Of The Galaxy apparance is hitting over $200 if it's in decent enough nick and the more recent series has seen issue 1 sell for over $30. While the Mike Mignola Rocket Raccoon limited series, a favourite from back issue bins over the last thirty years, now fetches $25 and Hulk #271 gets $50.
Time to go through those long boxes for some rodent action?
