All other arguments against the coin ploy aside, here's a fundamental problem with the scheme: Let's say it's
National Treasure 3, and Nick Cage's character breaks into the Treasury and steals the $1T coin. How much can he actually get for it on the open market? Is it
really worth $1T, or something in the general neighborhood? Or does it have a value -- as a coin -- equal only to its component metal(s)? Or something inbetween?
Or, more to the point, outside of the perception of value, how much is a $1T coin actually worth?
