Hello, my grandma just gave me a 1920's girl doll made in germany. The numbers on the back are 620-11.I saw one of these online for 50 but it didnt have the hair or the undergarment and the person said that it was a boy but another site that had it for sale said it was a girl. Mine has the hair with bow and the undergarment.What would something like this be worth just curious and would it be worth more later on down the road.Any more information is appreciated thanks!
