Harry Potter Books With Typos Can Fetch Thousands Of Dollars At Auction

It's sold over 400 million copies in almost 20 years, but not all copies of Harry Potter and the Sorcerer's Stone are created equal. In fact, Harry Potter books with errors could fetch thousands at auction. Here's how to tell if your copies of Harry Potter are worth any money.

The J.K. Rowling book in question is a first edition, hardcover copy of Harry Potter and the Philosopher's Stone. Bloomsbury published only 500 of these Harry Potter books with errors, but check your shelves — and library sales — anyway.

It's easy: just turn to page 53 and check out Harry's list of supplies for Hogwarts. If you see "1 wand" twice, BINGO! You've got a book worth at least £20,000 (about $28,000 U.S.). The Independent reports that one of these Philosopher's Stone copies "is expected to reach as much as £26,000 when it is sold at Bonhams Fine Books and Manuscripts Sale in London on [Nov. 9.]"

The first edition copies of Harry Potter and the Philosopher's Stone aren't the only Harry Potter titles to be worth serious galleons. According to AbeBooks, every installment in Rowling's main series has at least one edition that could fetch thousands of dollars from collectors.
