Here's a quick story for you people:
When I was in school (first school in fact) our teacher read us Harry Potter And The Philosophers Stone. I remember we nicknamed her "OneWand" as on the page where the list of stuff to buy for Diagon Alley appears, One Wand is listed twice in the list.
Turns out this was a mistake in printing on the FIRST EVER prints of the original paperback release which was quietly sent to a few libraries in the UK, that particular edition of the book is worth anywhere between hundreds and thousands of pounds depending on condition and is one of the rarest pieces of merchandise for HP fans. If it is signed by JK then it's worth tens of thousands!
I bet my teacher retired comfortably lol!
