How does the condition of an 80s comic book affect its overall market value?

Condition is paramount in determining value. A comic book from the 1980s in Near Mint (NM) or higher condition can be worth many times more than the same issue in Good (G) or Fair (F) condition. Flaws such as creases, tears, spine stress, missing pages, or water damage drastically reduce value. Professional grading by services like CGC or CBCS helps standardize condition assessment and can significantly increase market value for high-grade copies.
