I think this is a kind of Sympathetic Magic, and more specifically Law of Contagion. Original Mona Lisa is valuable in large part because it was in contact with da Vinci. A perfect replica would not have this quality. That's why mundane items that used to belong to famous people are often cherished.
It's interesting to read suggestion that Western culture might place more value in this "magical quality".
