I was curious to see if anyone could help me out.  
 
I have a book set of the first three Harry Potter books that are all HB. I know there was an article circulating on Facebook about a rare print of the first book having an error (on Harry's school list, it lists 'wand' twice.) My copy has it and are all in incredible condition.  
 
basically just wondering if there is anyone who could evaluate these books and tell me what they are worth? They are all third edition prints as well, however, from the research I have found that hardback copies of the original books do have some value (the first book was called philosophers stone but they changed it to the sorcerers stone).  
 
I'm looking to sell these to help cover some dental work and pay for text books for university.
