In the United States, approximately 135 million cars travel every day on the streets, roads, and interstates.

In Canada, the $1 and $2 come in the form of coins. The $1 is nicknamed a "loonie" because it contains a loon on it and the $2 is nicknamed the "twonie" because it is the equivalent of two "loonies."

The ridges on the sides of coins are called reeding or milling.
