Harry Potter is much more than just a bestselling series of fantasy books. Some editions of JK Rowling books have also become highly collectible even though the first one was only published in 1997 and the print runs have been huge.

At last count, AbeBooks had sold 55 Harry Potter books priced at $1.000 or more. In August 2005, AbeBooks sold probably the world’s most expensive Harry Potter book when a buyer spent $37,000 ($20,000) on an exceptionally rare first edition of Harry Potter and the Philosopher’s Stone.
