Things You'll Need
Instructions
If you're looking to sell your old collection for a bundle, it'll help to have some #1s (the first comic in a series) or issues that introduce popular characters.
Condition is key whether you're buying or selling; the cover is especially critical. Keep comics in top condition by sliding them into plastic sleeves with a piece of acid-free cardboard. Store protected comics upright on bookshelves in a cool, dry place.
Internet auctions offer the best access to other buyers and sellers of older comic books. Another good place to make a deal on older material is at one of the many comic book conventions.
If you're looking to unload more recent comics (5 or 6 years old), try a local comic book shop. That's also the place to look if you need just a couple of comics to fill out a series.
