It's difficult if you have a particularly large collection (several hundred or more), especially as the people best qualified to assess the value of our collections are we ourselves. Even toy dealers might not have the specialised knowledge of Transformers needed to give an accurate estimate of a collections value.

It might be good for us to cultivate some friendships with people who have a sideline as dealers, just to get them to countersign a letter confirming our estimation of the collection's value.
