Also why do some countries have the book title "Harry Potter and the Philosopher’s Stone" instead of "Harry Potter and the Sorcerer’s Stone"?

I just realized that I own a copy of the original first Harry Potter book (entitled Harry Potter and the Philosopher’s Stone). After only 500 copies were released in London, the title was changed to Harry Potter and the Sorcerer’s Stone. So basically, therer are only 500 copies in existance and I possess one of them.I read in a magazine that I copy was just auctioned off for 18,000$!!!! So my question is, how much could I likely get and do u know any good auction sites or info pages on this novel. Thanx!

My goddaughter (7 years old) gave me her favorite series, Harry Potter, and I promised her that I would read the first book by the next time I saw her. Well, I didn’t read it, and I see her in a couple of days, and I need some some to convince her that I read it. Don’t get me wrong, I had all intentions of reading the book, but I just never got around to it.

What can you tell be about "Harry Potter and the Sorcerer’s Stone"?
