What is this truck worth

Well I just purchased this truck about a month ago from my uncle, its been in a barn for about 39 years and is in perfect shape, no rust, floorboards and all still intact, what has me wandering, is the truck cab and the bed are made together, is this truck worth anything? It has white and black leather interior, 3 on the tree tranny, 292 v8 with original cross pipe above motor, original bias-ply tires from 62, not dry rotted either
