This is a system that I developed to determine how much my bobbleheads are worth for the purpose of buying, selling, and trading them. This way, I know if a trade is worth making and if someone is offering me equal value in return. My goal in sharing this system is to ensure that everyone can build up their bobblehead collection fairly without getting swindled in the process.
