About recognizing coins by feel...not all the Canadian coins are round, so that helps. The penny has 12 sides and the loonie has 11 sides. Some old nickels have "square" sides, maybe 10 or so (I've never counted), but the current ones are round. Also dimes and quarters (like in the US) have ribbed edges, while the others have smooth edges. Our new series of bills which just started coming out has Braille on them.

Here's a money-related question: what images do other countries put on their coins? Here we have
penny - maple leaves
nickel - beaver
dime - the Bluenose (a sailing ship)
quarter - caribou
$1 coin - loon
$2 coin - bears
Our bills all have famous Canadian guys (politicians) on them.

I can't even remember what is on the US coins, except the penny has a building on it, I think. Anyone else want to share?
