Where do I find valuation of figurines? - kaiser porcelain germany

I sell figurines and models of cars, etc. for my father and me to trade, eBay etc. Where can I find out what those reasons are really worth. In other words, like a porcelain figurine of Emperor (German) of the mare and foal Thoroughbred gawantka made by Wolfgang. If you have an idea that I heard.
