I'm not a doll type of guy but if you could prove the story/provenance regarding the Shirley Temple doll that would be incredible. Like anything else, lots depends upon condition, etc. Pictures of the three would be a help. Most dolls were played with hard and hence, the values are directly affected. Having not seen the dolls, I would guess they are probably circa late '40's to early '50's. My wife has her Shirley Temple doll along with a doll's trunk of her original clothes.
