My grandma bought a doll in the 70s and I can't find it anywhere. The doll person at the store told her to keep it because it would be worth something later. There is no identification on what kind of doll it is. I comes in a long slender blueish green box that has doll collectors written all over it. You open the bottom and slide her out. She is black and on the front of the box at the bottom it says "My name is Amanda 14063" What is she and is she wroth anything?
