Well to pocket the latest gold coin to be minted in Canada, it would have to be big enough to accommodate something 53 cm in diameter and over 3 cm thick. Your trousers would need to be strong enough to carry 100kg.
...and owning just one of these coins would make you a millionaire.
With a face value of 1 million CAD, the value of the gold is worth well over 2 million USD.
I got a 1oz Krugerand for my birthday once. If I put it on my birthday wish list, maybe I'll get lucky again.
