How to Protect Comic Books to Preserve their Value

Comic book collectors can make big money selling their books, but only if the condition is right. Protect your comic books the right way to help them maintain their value and bring you the price you want.


  • TIP: Don't use tape or other adhesives to repair tears in your comics. Even those marketed as archival quality can permanently damage the paper.
  • Step 1: Place your sleeved comics in acid-free boxes. Store the boxes in your stable storage environment. Inspect your comics periodically to be sure that they are remaining in top condition.
  • FACT: In 2010, a well-preserved copy of Action Comics No. 1 was purchased for $1.5 million at auction. The 1938 comic featured the first appearance of Superman.
  • Step 2: Insert a thin acid-free board into the sleeve with your comic to ensure it is stable and it will not curl in the box.
  • Step 3: Purchase sleeves made of mylar, a transparent, archival preservation quality film. Carefully insert one comic into each mylar sleeve.
  • Step 4: Locate a cool, dark, and dry place where you can store your comics. Don't store them in an area with direct sunlight, drafts, or temperature fluctuations. Avoid storing them in attics or basements.
  • TIP: Use an air conditioner and a dehumidifier to create a stable storage environment.
  • Step 5: Wash and dry your hands thoroughly before handling your comics to keep the oil from your fingers from staining the pages.
