Rowling will auction a hand signed, annotated first edition of Harry Potter and the Philosopher's Stone, containing insights into how she wrote it.
The book, to be sold by Sotheby's to benefit literacy charity English PEN, contains a note on Quidditch, which Rowling said "infuriated" men, 'The Telegraph' reported.
The 47-year-old author said she designed the game in a Manchester hotel room after an argument with her then-boyfriend.
"[Quidditch] was invented in a small hotel in Manchester after a row with my then boyfriend," she has written alongside the text.

"I had been pondering the things that hold a society together, cause it to congregate and signify its particular character and knew I needed a sport. It infuriates men which is quite satisfying given my state of mind when I invented it," she wrote.
As well as writing over 43 pages of her "second thoughts" upon reading the book again, she has also included 22 ink illustrations.
Others show a "brooding" Snape, the Mirror of Erised, Norbert the Norwegian Ridgeback dragon, and a man with two faces.
The book is one of 50 first editions to be sold at the auction, and annotated by their authors.
"This can undoubtedly be regarded as the definitive copy of any Harry Potter book," Dr Philip Errington, director of printed books and manuscripts at Sotheby's, said.
"Not only is it a fine copy of a first edition of the first book, but the author has significantly personalised it with numerous written comments and many impressive and evocative illustrations," Errington said.
