Big Coin, Big Deal

Canada has issued what they say is the world's biggest, purest, and highest denomination coin — a 220-lb, 21", 1.2" thick $1 million gold coin. Of course keep in mind that's a million Canadian dollars. It may be the purest and largest denomination — not to mention one that will really make your pocket bulge — but it's certainly not the largest. I've been to Sudbury, Canada and seen the big nickel. At 30-feet tall and 2" thick, it makes the $1 million coin look like chump change. Or at least a nano-coin.
