Hello, I will be visiting WDW next week and would like to begin collecting/trading pins. I have watched several videos to learn about the basic ins and outs of the hobby. One question I can't seem to find clear answer to is the value of pins. For example, I have interest in Beauty and the Beast pins, but if I find a limited edition Beauty and the Beast pin thats 10 years old for sale, is there a guide for me to follow at all to determine range of value of the pin? Or is as simple as how much someone wants for it versus how much someone is willing to pay? Im sure there is no short way to answer the question, is there a guide somewhere online to at least help? Thanks for any help in advance!
