A rare first edition of “Harry Potter and the Philosopher’s Stone” brought $81,250 at auction.

Heritage Auctions

WHAT: When an unsigned first edition of J.K. Rowling’s first title in her popular “Harry Potter” series hit a rare books sale at Heritage Auctions, few expected the result. By the time bidders were done, the book reached $81,250. The sum, more than four times pre-sale estimate, topped an existing record of $60,000 to set a new world record.

MORE: Released in June 1997, the title is now 20 years old. Only 500 first editions were distributed, all in England. They were issued without a dust cover, and 300 were pegged for British libraries.

SMART COLLECTORS KNOW: The title, “Harry Potter and the Philosopher’s Stone,” was used in the U.K. In the U.S., it was “Harry Potter and the Sorcerer’s Stone.”

HOT TIP: Consider the odds against this specific title surviving. Books are generally considered consumables intended to be read, then saved or discarded. No one saw Pottermania coming; only a clairvoyant would have known to stash away a first edition.

BOTTOM LINE: According to Heritage, the sale was the highest result for a Potter book at auction, plus the highest sum realized for an unsigned work of fiction published in the last 50 years.
