I have two breyers I have kept in the boxes and I am considering selling them. The first one I have is an original model of Barbaro. This is the one that comes with the certificate and has the golden signatre below its belly. This was the one that was out for a few days before it was retired. But they did make another model. How much would that be worth? Also, I have a model of Theodore O'Connor signed by both Karen and David O'Connor. The box and its right side are both signed by both of them. How much would this one be worth? I need to know as soon as possible. Please respond.

Thank you so much!
