What do you think a 1964 Coleman tent trailer would be worth today?

Coleman entered the tent trailer market officially in 1967 after the purchase of the Regis-Trimline company out of Milwaukee, Wisconsin. They started advertising in magazines like Better Camping and Camping Guide around November-December of 1966. Coleman did have tent trailers manufactured for them like the Carbana in 1960. If this is one of those trailers and is in decent shape it might have collectable value. Maybe it is worth donating or selling to a RV museum, like the RV Heritage Museum in Elkhart, IN?
