The ring cent or holey cent was a one-cent pattern coin first struck in various compositions and designs between 1850 and 1851 as part of an experiment on producing a cent with a reduced weight and diameter, as the rising price of copper had caused cents to cost more than their face value to produce. Many varieties exist, with differing designs as well as differing compositions, including billon (standard), aluminum, copper, cupronickel, nickel silver, nickel, silver, and white metal.
