I am new to this forum. I have in my possession a copy of the Hobbit and am wondering how much it may be worth?

The copyright page states:

Published by HarperCollinsPublishers 1999
Limited to a worldwide printing of 2,500 copies
This edition is based on the reset edition first published in 1995

First published by HarperCollinsPublishers 1991
Fifth edition (reset) 1995

Furthermore about 3 pages into the book one page has been "signed" (what i believe to be a printed signature) by Tolkien.

I have found a website with a similar looking book to mine and have listed it below.
