Value of Porcelain Doll?

I have a porcelain doll that has been in my family since I was 1, so it's 23 years old. She is a vintage female with a blue dress, hat, tights, shoes, etc. and stands about 3.5 feet tall. I am just curious to how much she is worth. She is still in the box and in fantastic condition. The tag she has underneath her on the box says Artmax, Chicago LTD/ OH 8325. If anyone has any suggestion to how I can find out much she is worth it would be greatly appreciated.
