Hello everyone. I am looking to sell my set of six figures from the Transformers Milk Caramel promotion. The six figures i have are from the Headmasters series, all yellow and are Slugslinger, Scorponok, Fort Max, Sureshot, Crosshairs and Sixshot. Problem is I have no idea what these are worth. They are all in C8 or better condition and I have almost never seen these before in all my years of collecting. I am told that they are very rare yet unpopular, so the value is low. I have checked all over the net and can't seem to find any sort of definitive value. I have someone offering me $20 each, I'm tempted to take the deal but I would hate to find out years later that these are worth $200+ each. Any insight would be greatly appreciated!
