A Trillion Dollar Coin

Platinum sells for $1,000/oz, so if it were to reflect its true value a $1 trillion Pt coin would weigh 28.5 kt (thou metric tons), be a cube 11.0 meters on a side, or, if it were the same thickness as a dollar coin (2 mm), have a diameter of 918 meters (3,010 ft). @axios https://t.co/Stt292P52Z
