How Much Is Amazing Spider-Man #121 Worth in 7.0, and What If Someone Drew on Gwen's Face?

In CGC 7.0, our FMV estimate for Amazing Spider-Man #121 is around $370 — a classic key at a still-accessible grade. Recent sales in our records show a CGC 8 fetching $640 and $599, and a CGC 9.2 hitting $1,000, so the market on this book is active and healthy. As for the Alfred E. Neuman doodle over Gwen's face — that's what graders call a "qualified" or simply a defaced/restored copy, and it would dramatically tank the value. A drawn-on copy like that would likely grade as a heavily defaced book, dropping it to a fraction of raw value — think bargain-bin territory, maybe $20–$50 if someone finds it charming as a curiosity, but no serious collector would pay key-issue prices for it. Keep Gwen's face intact, true believer — she's been through enough!
