Hello. I recently acquired a SKIPPER doll. She has on a tagged SKIPPER dress. Blonde hair, double bangs, holes in bottom of feet which are marked USA. Her knees bend and her bottom is marked c. 1963 Mattel Inc. Can anyone provide more info? Is this a sample, prototype doll, etc? Also I won't be selling but am interested in knowing the approximate value in the event I decide to. Thank you in advance
