What is the value of the 1931 first edition of 'Good Earth' by Pearl S Buck?

A true first edition in fine condition with a fine dust jacket could be worth as much as $15,000. Without the dust jacket, the book is worth a few hundred dollars depending on condition. The true first edition can be identified by the "flees for fleas" typo on page 100 where it says "the small mat sheds clung like flees to a dog's back." In later printings it was corrected to say "the small mat sheds clung like fleas to a dog's back."
