A penny is a unit of currency that typically represents one cent, which is one-hundredth of the primary unit of currency in countries like the United States, Canada, and some others. In the US, a penny is usually a one-cent coin made primarily of zinc, with a thin layer of copper. The design of the penny has featured various figures, most notably Abraham Lincoln since 1909.
