Could you please provide a color picture. From what I can tell, it's a 2000-S Proof. It's probably worth a few dollars but I can't really give you a grade without seeing a better picture. As for what you paid, I think you did fine. It's not a steal but not a rip off either. Also, could you please post a more specific title than "Whats it worth?" from now on. Some people find vague title's like this rude on a forum. You would be better off saying something like "What's my new Sac worth?"
