Don’t panic if your copy is a bit dog-eared or has a juice stain on page 47. Condition is crucial. A book that’s been chewed by a Kneazle isn’t going to fetch top dollar. But a “very good” copy—no torn pages, no writing inside—can still be worth thousands.

Also, that second or third printing you own? It’s still a cool book. It’s not a million-dollar item, but you can probably sell it for a nice dinner out. Or a lifetime supply of pumpkin juice.
And hey, if you find a signed copy of any edition, you’re in a different league. Even a later edition signed by J.K. Rowling can be worth a small fortune. She famously has a fantastic signature. It’s like a magical autograph.
