5 piece floral nesting doll

I found this doll at a local yard sale. From what I can tell, all pieces are there. It's hand painted with a floral pattern, has a beveled bottom, the wood isn't discolored, and has minimal chipping. However there are a few noticeable...mistakes. For example, the first two outer dolls have two strands of black hair curling in the middle of the face, the second largest doll also has somewhat of a lazy eye, one of the dolls has a pink dot (the same color as the flowers) in a place where there are no flowers, the smaller the dolls get, the sloppier/rushed the details get, the lips on the first doll appear to be unfinished, and the bottom of each piece has a small square shaped hole in the bottom. I haven't been able to find anything like them online and I would love to find a rough estimate on what they may be worth.

Good
