Rare Harry Potter book fetches $19,120 at auction

A first-edition Harry Potter book was sold for about $19,000, at an auction. Harry Potter and the Philosopher's Stone includes an autograph from author JK Rowling.

The paperback was one of 200 copies printed and is a rarity compared with later editions of the popular series that were printed in the millions, according to auctioneers, Heritage Auction Galleries said.

The auction in Dallas, US, had estimated that the 223-page book would sell for as much as $12,000. Last year, an 800-word prequel to the blockbuster Harry Potter novel series fetched nearly $50,000 for a writer's group and dyslexia charity.
