Toys are not the only childhood items you can resell for a profit. Books can also be resold for a pretty penny, especially if they are a first edition copy of the wildly popular Harry Potter and the Sorcerer’s Stone. Those can sell for up to $6,500.
In general, first edition copies of books are the most valuable. A first edition of the magic-centric novel signed by author J.K. Rowling herself could go for a whopping $15,000. These books are especially valuable if you have not lovingly dog-eared all of its pages! How to recognize the highest bidder? He’ll be the one wearing glasses and waving a stick around.
