When Canada introduced its 1-dollar coin in 1987, it became known as the “loonie” for the loon on its back.

When the Royal Canadian Mint introduced the 2-dollar coin in 1996, Canadians tried hard to find a comparable nickname. Though “toonie” or “twoonie” eventually won out, the list of failed suggestions included “doubloonie,” “doozie,” and the charming “moonie.”

Why moonie? Because the coin depicts the queen “with a bear behind.”
