JK Rowling net worth keeps soaring thanks to broadway, merchandise

JK Rowling Net Worth: $1B

Easily the most successful author in history — from a financial standpoint, at least — J.K. Rowling is the author of the "Harry Potter" series. In addition to the "Harry Potter" books, Rowling has written a number of related one-offs, published crime novels under the pseudonym Robert Galbraith and written the screenplay for the movie, "Fantastic Beasts and Where to Find Them."

'Harry Potter' Books

If you have first-edition or classics, you might be able to fetch some cash for those collectible books. Hardcover first editions of "Harry Potter and the Philosopher's Stone" can fetch up to $45,000 and "Harry Potter and the Chamber of Secrets" can go for around $7,000, according to Sotheby's. A first edition of F. Scott Fitzgerald's classic, "The Great Gatsby," however, could sell for as much as $400,000 — as long as it's in a perfect dust jacket.

Books can be highly valuable depending on a number of reasons and factors that include rarity and binding quality, according to auction company Sotheby’s. Before you trash or decide to rebind your books, do your research — you just might have a gem in your hand.
