It becomes a bit of a thought experiment.

All or most of us have items that are ridiculously, extremely rare, and in our minds they could easily be traded for a dump truck full of gold. That's how rare they are, and we hold onto them. But if we actually tried to sell them? Market forces would clear the wonderful optimism from our heads, and the amount of gold we walk away with wouldn't fill the back seat of a convertible Hot Wheels* car.
