$1 million coin
The crazies in Canada have created a $1 million coin. The coin weighs 220.5 pounds and is 21 inches in diameter. The hand crafted coins will be produced in extremely limited quantities, and at 99.999% purity, the gold in the coin is actually worth more than twice its $1 million face value. Which just sounds stupid. If you bought it and melted it down you'd already have doubled your investment. Or if you got me to sign it you'd have quadrupled it.
