I need help. My friend has this vintage GI Joe doll that is mint in box never opened and I cant find out anywhere what it might be worth. He wants me to sell it on ebay for him and he thinks its worth $250. I did my own research and found that loose vintage dolls are going for this price. Is there anyone out there who is a GI Joe collector and can help me out? I do not know the name of the figure or the year but I can find out. Your help will be greatly appreciated.
