If you can believe it, the novel Harry Potter and the Philosopher's Stone - AKA the first in the series - was released a whopping 22 years ago in 1997. Feeling old yet?
And whilst most Potter super-fans had the original copy of the book with that now-iconic illustration on the front of Harry at King's Cross on Platform 9-and-three-quarters, there was actually an incredibly rare hardback version of that... With only 500 copies made.
Today, a couple from Lancashire sold their first-edition copy of the book at an auction - and earned a huge £57,040 for their rare version. Choosing to remain anonymous, the couple decided to sell it - and it went for almost £30,000 more than they'd expected.
The couple revealed that they'd been hoping to keep the book as a family heirloom, and have kept the novel locked up in a coded briefcase along with a similar edition of the second novel in the series, Harry Potter and the Chamber of Secrets, for over 20 years - meaning it's in excellent condition.

"It goes without saying that we’re absolutely delighted with the price achieved. The book was given to us as gift by an aunt when our children were small. She bought it at an independent book shop when it was first published."
