The cent, the United States of America one-cent coin, often called the "penny", is a unit of currency equaling one one-hundredth of a United States of America dollar. It has been the lowest face-value physical unit of U.S. currency since the abolition of the half-cent in 1857. The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. Due to inflation, pennies have lost virtually all their purchasing power and are often viewed as an expensive burden to businesses, banks, government and the public in general.

The cent is a monetary unit of many national currencies that equals 1⁄100 of the basic monetary unit.
