Rare Plastic Figures

These are three of my rarer figures. Two of them I believe are Dan Dare figures I got from Ebay some time ago. I don't know much about their value and history but believe them to be worth at least fifty dollars each. The middle figure looks like Charbens to me. My friend from Adelaide, Brenton Hoffman, offered me $20 each but I'm sure they are worth much more. Any information on them would be welcome.

Well, I did some research and found out that the two space figures are from the Kentoys Dan Dare set and worth about $50 each. The lady in national costume is Charbens.
