It's worth noting that the comic book's condition, whether it is unrestored or professionally restored, can greatly impact its value. As with any collectible, a certificate of authenticity from a reputable source adds value and ensures its legitimacy. The comic book market is subject to fluctuations based on market demand and conditions, so it's always a good idea to consult with a professional comic book appraiser or dealer to determine the exact value of a specific copy.
