If you own a copy of the book Harry Potter and the Philosopher's Stone, there’s a chance it could be worth tens of thousands of dollars. How do you know if yours is one of the 500 hardbacks with the rare mistake? Go to page 53, and look at the list of school supplies recommended for incoming Hogwarts students. If “1 wand” is on there twice, you could be sitting on a small fortune (that is, if your copy is still in good condition). As Time and The Independent note, one copy might bring more than $30,000 at an auction this fall.

As an official at Bonhams Fine Books and Manuscripts, who is hosting the auction, explained to The Independent, “Like most enduring books aimed at younger readers, the Harry Potter books also have wide appeal to adults and there is a strong market among collectors for first editions.”

Here’s a look at the passage a Twitter user discovered back in 2014:

Pottermania is alive and well. This weekend, the script for Harry Potter and the Cursed Child—a two-part play that picks up where J.K. Rowling’s Harry Potter series ends—was released in book form. Well, the sales numbers are in. And they’re staggering. Scholastic announced that Cursed Child has already sold more than 2 million copies in North America alone. It’s been out for two days.

Two days.

Oh, and that doesn’t include e-books (which aren't sold through Scholastic).

It’s already one of the fastest-selling books in history, according to Vulture. But even then, Cursed Child falls far short of the seventh book in the Potter series, Harry Potter and the Deathly Hallows, which sold an absurd 8.3 million copies in 24 hours. (And even got reviewed by none other than Christopher Hitchens.) Discuss

Tim LaHaye, who co-wrote the best-selling end times series Left Behind, has passed away at the age of 90. The series of novels was based on a literal interpretation of the Book of Revelation, and went on to sell more than 80 million copies and spawned several movie adaptations.

Though he’s probably best known for his novels, LaHaye was an influential figure in Christian education—he founded San Diego Christian College, the Institute for Creation Research, a dozen Christian secondary schools and Liberty University’s Tim LaHaye School of Prophecy. In a statement, his Left Behind co-author Jerry Jenkins said, “Thrilled as I am that he is where he has always wanted to be, his departure leaves a void in my soul that I don't expect to be filled until I see him again.” Discuss
