Troll dolls

This is a 1980's Dam troll Dolls. Dam is the original maker of troll Dolls from the 60's. I've had this since before I can remember. they belong to my older brother before I was born. I am now 40 and no longer want them. They are very collectable some go for alot of money. I haven't really looked into them. Just need the space i have several.
