How much would a china doll made out of elephant tusk be worth?

I want to make some extra cash quick, and I realized that I have a china doll made out of elephant tusk. It was given to my grandmother when she was an adult (so a longgg time ago) by a couple who came from another country. When my grandmother died, she gave it to my mother who gave it to me, and now I would like to know how much it's worth. Any ideas?|||The first thing you want to do is get it appraised; see if it's real ivory, and if it's a real china doll or a family heirloom. You'll have to do this first to find a value. Take it to a pawn shop, or some place that knows about things like that.
