6. The Tales of Beedle the Bard – $3.98 Million
In addition to the Harry Potter series, J.K. Rowling also released The Tales of Beedle the Bard, a book that first appeared in *Harry Potter and the Deathly Hallows* as a farewell gift from Professor Dumbledore to Hermione. Having grown up in a pure-blood wizarding family, Ron was already familiar with the fairy tales in the book, while Hermione and Harry, raised by Muggles, had never heard of it. The most important part of the book is the story of the Three Deathly Hallows as told by Xenophilius Lovegood in *The Tale of the Three Brothers*: the Philosopher’s Stone, the Elder Wand, and the Invisibility Cloak.
This highly valuable book was handwritten and illustrated by Rowling herself, who decided to donate the proceeds from its sale to the charity campaign *The Voices of Children*.
