What are they worth??

Greeting Fellow F-Chatters. My wife and I moved into our Drem home last Ocober, and I've finally finished my "ManCave" Ferrari Room. I've recently aquired some items, and I was wondering if anyone would be able to help out with your expertise and help me assessing their value.

1. I was given a used Nascar Good Year Eagle Tire. It's got all sorts of Markings on it. It appears to be the The Left Front tire from car # 88 (Dale Jr.). Not Ferrari, But Very cool to have None the less.

2. A "barbie sized" Michael Schumacher Figurine (Doll) The box and doll are in Pristine condition. It's Never been opened. From What I can se, It comes with a Certificate of Authenticity Siged by Jean Todt, Michael Schumacer and Another Signature that I cannot make out because the Doll is covering it. Michael is decked out in full Ferrari Gear, and he's holding his helmet under his right arm. On the Front of the box, It says that it is a Limited Edition Collectors Figure. It has an Official License # AB 6746Xm tag on the bottom of the Box.

I have absolutely No idea of what value these may hold. Any assistance would be greatly appreciated.

Thanks

Anthony
