The Liberty Head nickel was heavily struck during its 30-year run, except during economic downturns in 1885â1886 and in 1894, when only small numbers were struck. In 1890, Congress ended production of the three-cent piece, leaving the five-cent coin as the only one in copper nickel. That year, Congress also allowed the Secretary of the Treasury to authorize the redesign of United States coins, if the former design had been struck for at least 25 years.
