I'm slightly mystified at the sums collectors items sell for. It seems intuitive to me that their prices should be some function of their inherent values, however that's calculated. It could even be many times that number but it should at least be tethered to reality.
Obviously the original Mona Lisa is worth a bit more than a good copy.
I suspect we are.
