Determine the condition of the comics by looking for any signs of wear and tear or damage. If the books are in good condition you should protect them by using comic bags and boards.
Set the comic books into different categories depending on the publisher or main character. It may be helpful to place all independent comics into one area and all main characters into another. Buyers often look for books starring their favorite character or those from one specific publisher.
Decide the best way to sell the books based on their value and condition by looking through an up-to-date price guide. If the majority of your books are fairly common it’s best to list them in a box lot or to list a set of ten or twenty together. Those rarer or more valuable books can be listed separately.
Take clear pictures of the comic books using a digital camera. Check the pictures to make sure all flaws or damages are clearly displayed and take additional pictures when needed.
List the comics online at an auction site or in a classified ad. Write a clear description of the books including any damages and exactly what is included in the listing. By following these steps, you can sell those used comics fairly quickly.
