Antique China Head Doll

I was given this doll when I was alittle girl ( I'm now 31). I was told it was my great great aunts and that she got it from her grandma or great grandma, so I'm guessing it's over 100 years old atleast? When I was little my mom put a different dress on it which makes the value go down. It also has paint missing on head. There is a number 3 stamped in back of plate of the neck area. It's body is made out of some sort of straw? I haven't been able to find another doll that's exactly like this body. I'm just wanting to know how old it is, possibly how much it's worth, anything about it I guess.
