Books from the "Harry Potter" series by J.K. Rowling may fetch their owners a pretty penny according to "J.K. Rowling: A Bibliography 1997-2013." This book, which is a compilation by Philip W Errington, lays out which of the "Harry Potter" titles and format is worth more than the Harry Potter experience.
According to Uproxx, the details in "J.K. Rowling: A Bibliography 1997-2013" came from Philip W Errington's experience from the auction events at the Sotheby auction house. The older the "Harry Potter" book, the bigger the amount they can fetch. As example, Bloomsbury's edition of "Harry Potter and the Philsopher's Stone" in hardback where the cover displays Harry Potter standing by a train is a rare print.
This "Harry Potter and the Philsopher's Stone" title is even more rare when the author named is Joanne Rowling, the name under which J.K. Rowling initially wrote. "J.K. Rowling: A Bibliography 1997-2013" quotes AbeBooks in saying that this specific "Harry Potter and the Philsopher's Stone" edition can auction for as much $55,000.
AbeBooks is an online book site, which expertise lie in rare book editions. Based on AbeBooks' assessment, the re-sale price for specific "Harry Potter" editions may be around almost $300 (£200) to more than $50,000.
The Independent reports that AbeBooks indicates that US first editions of J.K. Rowling's "Harry Potter" books fetch the heftier auction yields. "Prices for first edition first printings go up to around $6,500 with a fair selection between $4,000 and $5,000 - many signed by the author - although cheaper copies can be found." These books have the following information on the copyright page: 1 3 5 7 9 10 8 6 4 2 8 9/9 0/0 01 02 / Printed in the U.S.A.23 / First American edition, October 1998.
