If you happen to have the hardcover first editions of “Harry Potter and the Philosopher’s Stone,” it’s worth your while to check for a specific print line, “10 9 8 7 6 5 4 3 2 1.” This particular edition of the book could fetch a remarkable value of up to $55,000.

Moreover, if you own the American versions of the series, like “Harry Potter and the Sorcerer’s Stone,” you might want to inspect them for a particular print line: “1 3 5 7 9 10 8 6 4 2 8 9/9 0/0 01 02,” typically found on the copyright page. In such cases, these editions can also be quite valuable, with potential resale prices reaching up to $6,500.
