Dust off your bookshelf: Harry Potter books now worth $50,000

It is rare for the first edition of novels to appreciate in value on collector markets but sometimes, it does happen.

Luckily for J.K. Rowling, certain copies of her novel series, Harry Potter, have done just that. According to Mashable, certain first releases of the novels are now worth $50,000. These first releases are unique. For example, first printings of Harry Potter and the Philosopher's Stone list the author as "Joanne Rowling" instead of J.K.. This book's particular printing had only 500 copies printed, 300 of which were donated to libraries.
