We have this small Thief Gold guide made by Prima Games. My girlfriend bought a few years ago. It was the only one on Amazon at the time. Now I'd like to get a value for it for record purposes. This copy is the only one she has ever seen for sale anywhere. I did a search to see if I could find it for sale anywhere earlier today and came up empty handed. The only information I found was the basic publishing information about the guide. Did a search here and didn't see any previous threads about it. Below are pictures of the front and back. I know what she paid for it, but I am curious what the community would say its worth. So what do you guys say?
