Harry Potter book sold for £9,000

The first edition was sold on a commission bid

A rare first edition of a Harry Potter book has sold for £9,000.

The copy of JK Rowling's Harry Potter and The Philosopher's Stone was sold at Bonhams' Books, Maps, Manuscripts and Photographs Sale in London.

The book, one of only 500 published by Bloomsbury in 1997, had a pre-sale estimate of £5,000-£7,000.

Bonhams sold the hardback on behalf of a woman who had bought it originally with book tokens she had been given as a school prize.

Last week a student sold his first edition of The Philosopher's Stone - the first book in the series- for £7,200 at auction.

Toby Rundle, 19, from Somerset, auctioned the hardback copy in order to fund his university degree.

Mr Rundle was sent the book by his mother while he was at boarding school.
