A rare first edition of a Harry Potter book has sold for 36,000. Christine McCulloch bought the copy of Harry Potter and the Philosopher's Stone for her son Adam in the 1990s. She said she paid about 10 Euros for the copy from a bookshop in Stratford-upon-Avon in 1997 and had no idea the same book would be worth thousands of pounds, 30 years later. On Wednesday, the first edition was sold at Rare Book Auctions in Lichfield, Staffordshire, with the buyer paying 45,000 Euros in total with a buyer's premium.
