Insider spoke to three Barbie collectors who seem unfazed by the potential rise in the dolls' worth. As a collector doing it for love, he told Insider those looking to make money should invest in other things. Antique expert Dr. Lori told Insider she estimates a 25% rise in the doll's value in the build-up to the film's release and immediately afterward. "There are too many elements to the concept of value, and it's rarely just about finance," Yang told Insider. Even if these Barbie collectors were looking to make a quick buck in Gerwig's box office weekend, selling Barbies isn't easy.
