One wizard's typo is another Muggle's treasure.
Bet you're wishing you had a Time-Turner right about now so you could back to 1997 and purchase one of the 500 hardback copies of "Harry Potter and the Philosopher's Stone" that have a very costly gaffe.
Fortunately for people who do have this early version of the novel, it's worth enough of a small fortune for you to consider opening your own Gringotts bank account.
"OH HELLO MR. GOBLIN? I'D LIKE MY OWN VAULT."
On page 53 of "Harry Potter and the Philosopher's Stone," the item "1 wand" is listed twice underneath the list of "Other Equipment" that all first-years need before attending Hogwarts.
Wait, which is it? One wand or two wands? How many wands do I effing need, Dumbledore?
Needless to say, this typo would have never happened had Hermione been in charge of editing the book.
But all the mischief of the typo has been managed.
In fact, one book containing the error is set to be sold for over $33,000 at November 9's auction at London's Bonhams Fine Books and Manuscripts, a place that totally sounds like it's operated by a 762-year-old wizard in Diagon Alley.
Bonhams head of books and manuscripts, Matthew Haley (not a 762-year-old wizard), had this to say about the typo,
In case you were wondering, if I were to look into the Mirror of Erised, I would see me holding one of these 500 copies. Or 500 of these 500 copies.
