The Tales of Beedle the BardSANG TAN/AP/Shutterstock
JK Rowling’s first book since the conclusion of the Harry Potter series fetched a huge chunk of change. Published in December 2007, Beedle was the complete book of fairy tales that play a crucial role in the final installment of the Harry Potter series. JK Rowling produced seven separate handwritten copies of Beedle, filled with illustrations she herself had drawn. These books were incredibly beautiful: leather-bound, with silver and moonstones decorating the cover. Rowling gave six of these “Moonstone Editions” to friends and people who worked on the Harry Potter books, but one went up for auction on Amazon. One mega-fan paid $3.98 million for it, and Rowling donated the proceeds to a children’s charity. While far from the most expensive book on this list, Beedle was the priciest book ever purchased that was written and published in the twenty-first century. If you own one of these rare books, you’re sitting on a gold mine.

The title of this eighteenth-century French handbook translates to “Treatise of Fruit Trees.” The book was written by botanist Henri Louis Duhamel du Monceau and contained five separate volumes filled with detailed illustrations. This manuscript went for 3.4 million euros (about $4.5 million U.S.) at a 2006 auction. Yes, someone spent four-and-a-half million dollars for a book about fruit trees.
