Thank you for contacting Mearto with your appraisal inquiry.

It is a cute doll. Such vintage toys are being offered at auction on a regular basis.
From the photos it appears that the body is made of some kind of softer material like vinyl and the head is made of celluloid, the forerunner for plastic. The squeezer in the stomach was a feature that was new in the 1940s-1950s. And the materials used was typical of dolls from the middle of the 20th century.
The value of all your dolls is determined by the company that made them and how many dolls were made from each lot. Normally these companies produce dolls in lots of 1000 to 2000 dolls. Without any marks or numbers it is hard to say where the doll was produced as there were many different factories that produced dolls during the 20th century.
The collectors are primarily interested in dolls with porcelain heads which is visible in the appraisal.

The estimate provided is for a well-advertised specialised online toys auction, where I believe the doll has the best chance of realising its fullest potential. However, there is no measurement for the sentimental value you might attach to the doll. Retail "asking prices" can be higher and vary.

Please let me know if you have any additional questions. I’m happy to help.
Thank you
