A 2-dollar coin was introduced in 1997. In 2001, nickel-plated steel replaced cupro-nickel in the 10, 20 and 50 cents and 1 dollar coins, and a bimetallic 5-dollar coin was introduced. The Reserve Bank of Zimbabwe announced plans for new Z$5,000 and Z$10,000 coins in June 2005,[60] although these were never actually struck.
