Annotated Copy of Harry Potter and the Philosopher’s Stone

Because there were only 500 UK first edition copies made, surviving books can earn their owners around $56,000. Add in handwritten annotations and illustrations from the author and you’re looking at $228,000.

Harry’s Glasses

His iconic spectacles were one of the most important props in the film, which is reflected in their selling price of $20,000.

The Golden Snitch

One lucky bidder just decided he’d buy it – for $7,000. It’s not actually made of gold. It’s a plastic ball covered in gold paint.

The Elder Wand

=The Elder Wand is one of the most sought-after and powerful items. It sold for $10,100 at a premier props auction back in 2013.

J.K. Rowling’s Chair

This chair stood in JK Rowling’s kitchen in Edinburgh and was where she sat to write the first two books in the series. It was sold for $21,000, with the proceeds going to children’s charity Books Abroad. It was auctioned off again online several years later, then resold for a whopping $394,000 at a rare books auction this past April.

Original Philosopher’s Stone Cover Illustration

The fantasy series original art could fetch you around $100,000. It was bought by a private American collector when it was auctioned at Sotheby’s London.

The Tales of Beedle the Bard, Handwritten by Rowling

The most expensive Harry Potter book isn’t even a part of the original series: it’s a handwritten copy of The Tales of Beedle the Bard. The book is a story-within-a-story mentioned in The Deathly Hallows , and has been inscribed by Rowling herself in a five-volume, leather-bound and silver-embellished series. The book earned £1,950,000 (nearly $4 million) for the charity The Children’s Voice.
