1st Edition Potter Books Worth a Fortune It may only be a few years old, but your Harry Potter book could be worth a fortune! Some of the rarest books are selling for hundreds, if not thousands, of pounds. The most valuable is the original first edition hardback of The Philosopher's Stone. Only a few hundred copies were printed in 1997, when it cost less than £10. Now, they can sell for a mindboggling £15,000. Experts can tell what edition a book is by looking at the publisher's information page at the start of the book. There's usually a series of numbers. If it counts down from 10 all the way to 1 that means it's a first edition - in other words, the first copies to appear in the shops. It may seem silly, but first editions are worth a lot of money, particularly for rich collectors in the United States, probably because they're so hard to get hold of. The Deluxe editions are also worth a lot of money. The most difficult to get hold of is first edition of The Prisoner of Azkaban, which was originally £18 in the shops and is now worth £2,000. And if you were one of the lucky people who got their Goblet of Fire signed by J K Rowling last summer, even they are selling for up to £500.
