A book by JK Rowling about the world of Harry Potter has gone under the hammer for a massive £1,950,000!
The Tales of Beedle the Bard is mentioned in the final Potter book, but is one of only seven copies in the whole world.
The Harry Potter creator, who watched the auction live on the internet, told Newsround that she was "stunned and ecstatic" at the news.
Money raised from the seventh copy will go to the Children's Voice charity.
JK hand wrote the jewel-encrusted volumes of short stories and gave six of them to her friends who had helped and supported her while she wrote the seven Potter books.
She told Newsround: "I'm stunned and ecstatic. This will mean so much to the children desperately in need of help. It means Christmas has come early for me."
The book was bought by a picture dealership from London called Hazlitt, Gooden & Fox. They are a company which normally buys paintings and drawings.
In Harry Potter and the Deathly Hallows, Dumbledore leaves a volume of the tales to Hermione Granger.
The stories provide clues to help Harry and his friends defeat Lord Voldemort.
The Tales of Beedle the Bard
The Fountain of Fair Fortune
Babbitty Rabbitty and her Cackling Stump
The Wizard and the Hopping Pot
The Warlock's Hairy Heart
The Tale of the Three Brothers
One of those is The Tale of the Three Brothers, and three others are mentioned in Deathly Hallows too.
But there is one brand new story in the seven real books.
The copy which went under the hammer in London was mounted with silver ornaments and seven moonstones.
In the front of it, Rowling wrote: "Six of these books have been given to those most closely connected to the Harry Potter books during the last 17 years.
"This seventh copy will be auctioned; the proceeds to help institutionalised children who are in desperate need of a voice.
So to whoever now owns this book, thank you - and fair fortune be yours!"
