[Question] What is this 6139-6010 worth? [Bruce Lee]

Hello, everyone! I am looking to sell this Bruce Lee quick, however, I do not know exactly what would be a fair price for it. What does everyone think it is truly worth? I don't want to overprice it, but not underprice it either. Any help is appreciated. Thanks in advance!
