Bi-metallic coins are coins consisting of more than one metal or alloy, generally arranged with an outer ring around a contrasting center. Common circulating examples include the €1, €2, British £2, Canadian $2, South African R5, and Turkish lira. Bi-metallic coins have been issued for a long time, with examples known dating from the 1600s, while the Roman Empire issued special occasion, large medallions with a center of bronze or copper and an outer ring of orichalcum, starting with the reign of Hadrian. The silver-center cent pattern produced by the United States in 1792 is another example. In recent times, the first circulating bi-metallic coin was the 500 Italian lire, first issued in 1982. France, with a 10 franc coin and Thailand, with a 10 baht, issued bi-metallic coins for circiraulation in 1988.
