In Man in the High Castle, Philip K Dick calls this historicity. A shopkeeper shows two necklaces, indistinguishable from each ither but one was worn by Sitting Bull and the other is a fake. One has historicity and the other is basically worthless. But the knowledge of the historicity is inspiring and makes it valuable. The power of human perspective.
I like the idea that if you took both necklaces and shuffled them around in a way that neither you nor the shopkeeper knew which was which and then gave them both back to him, you would have essentially robbed him without taking anything from him.
