On an item like this it all depends where you are and who wants it at that time.
I have seen them sell from $600 clear up to $1800 at toy auctions.
I have seen them with a price tag of $2500 at shows. Did it sell? I don"t know. But that doesn"t mean they are worth $2500 cause someone has one for sale at that price.
Very tough to put a value on any collectable item and say that is what it is worth.
