Don’t just throw your old books away especially if they include any of the earlier publications of the famous “Harry Potter” series. The first editions of the stories of the beloved boy wizard will fetch you a handsome fortune if your book is written by Joanne Rowling instead of J.K. Rowling.

The Sun reveals that Mr. Philip W. Errington, an author, has collated data indicating the worth of the early editions of the wizard’s tales. Errington collected the information when he was with Sotheby’s auction house. The author is set to divulge his findings in a new book entitled, “J.K. Rowling: A Bibliography 1997-2013.”

The first “Harry Potter” book was published around 20 years back. The hardbound edition by Bloomsbury is expected to fetch its owner a hefty AU$76,000, informs The said edition features a young Potter standing by the Hogwarts Express. If you don’t have a hard cover one, fret not. The softbound edition would also fetch its owners a decent sum. A soft cover of the first book or a hard cover edition of the second installment is expected to earn a decent AU$12,500. The third book, “Harry Potter and the Prisoner of Azkaban,” is expected to get AU$900, notes

So, how can a book lover be sure that he/she is sitting on a gold mine? According to ABE Books, owners will be able to tell if they have the prized editions based on the print line and author credit. The website further states that the print line should consist of numbers, “10 9 8 7 6 5 4 3 2 1.” Also, the author credit should go to “Joanne Rowling” and not J.K. Rowling.

One of the reasons for such crazy worth is the fact that the first editions of the “Harry Potter” series, particularly “the Philosopher’s Stone,” are considered the “Holy Grail,” explains ABE Books. The website further explains that only 500 copies of the first installment were ever printed, out of which 300 were donated to various libraries.

Go back to your book cases, check your “Harry Potter” books, and uncork the champagne.
