I have an old Cabbage Patch doll still with tags and not she hasn't
really been played with. It is a signed doll fron 1985...signed by
Xavier himself. There is a small bit of dirt on the dolls nose
however, but she is in all original clothing. I was curious how much
she would be worth if i wanted to sell her.Thank you for your answer.

xavier dolls from 1978:
