The Tales of Beedle the Bard, J.K. Rowling — $3.98 million
Before this book, meant to be the same children’s book that figures heavily in Harry Potter and the Deathly Hallows, became a mass-market paperback, J.K. Rowling created seven original copies, each one handwritten and illustrated by Rowling herself. Six were given to friends and editors, but in 2007, one of the seven was put up for auction. It was snapped up by Amazon.com for a whopping $3.98 million, making it the most expensive modern manuscript ever purchased at auction. The money from the sale of the book was donated to The Children’s Voice charity campaign.
