Thank you for submitting your item for appraisal. This appears to be a group of korean made dolls of ca. 1990 sold under the brand name "Seymor Mann". The were sold on TV and in department stores during the then thriving porcelain doll boom. The general taste has shifted and prices are down. The estimate is based on similar lots sold at auction recently. There is no measurement for the sentimental value you might attach to the dolls.
