Thank you for submitting your item for appraisal. This appears to be a group of travel dolls produced by Duchess Doll Corp 1948-1950s and other manufacturers. These hard plastic dolls were meant to be collected and thus many have survived, even boxed as the ones in your possession. They were inexpensive then and although they are quite pleasant to look at the demand is limited today. The estimate is based on similar sold at auction. "Asking prices" in the trade can be higher and vary. There is no measurement for the sentimental value you might attach to it.
