Some fun Penny facts courtesy of the Canadian Mint.
>  35 billion pennies have been minted since 1908, and the total weight of all those coins  (103,617 tons) is almost double that of the Titanic.
> At 2.35 grams, a penny weighs about the same as a hummingbird.
> If all those pennies are stacked up, the height (52,600 kilometers) is the equivalent of about 100,000 CN Towers, the iconic edifice in Toronto.
> If placed side by side, all those Canadian pennies would circle the earth 16 times
