What if the U.S. Treasury minted a coin from $1 trillion worth of platinum?
Such a coin would weigh 42,778,918 pounds — the equivalent of nearly seven Saturn V rockets — and occupy 31,947 cubic feet.
What would this coin look like?
If it had the same proportions as the U.S. dollar coin, it would be roughly 80 feet wide and 6 feet thick. Though not a very practical coin, it would have the benefit of being really difficult to steal. And you could see it from space.
But commodity money disappeared a long time ago, so let’s say the government decides to mint an actual trillion-dollar coin, and makes it out of pure platinum at the same size as the U.S. silver dollar; though the coin would be worth $1 trillion, the platinum itself would only be worth a bit more than $1,200.
[Calculations assumed $1,593 per troy ounce of platinum.]
