If you’re lucky enough to own an early edition of J.K. Rowling’s Harry Potter books, one from before the series took over the world with movies and theme parks and video games and the rest (yes, such a time did exist), then you may stand to make a pretty penny. Case in point: a schoolteacher recently brought her early editions of the first two Harry Potter books on Antiques Roadshow, the show the BBC show where antiques experts tell people how much their old crap is worth. It ends up that the teacher’s books, together, are worth anywhere from $2600 to $3900. What’s in your attic?

The schoolteacher’s copy of Harry Potter and the Philosopher’s Stone (the British title for the book) is not a first edition, but contains something far more valuable: A handwritten note from J.K. Rowling herself! How exciting is that!?

To the Pope family, with many thanks for introducing Harry to so many people, JK Rowling.

However, the second book she owns, Harry Potter and the Chamber of Secrets, is a first edition, and also had a little note from J.K. Rowling. This teacher was definitely onto something early on, wasn’t she?

It turns out when the books first started coming out some 20 years ago, the teacher read them to her students and took them to see J.K. Rowling when she was doing a book signing. She recalls the children being super-excited and how Rowling spent nearly an hour with them. Those children sure did get some amazing memories as a result!
