In 1982 the penny replaced into replaced from the classic alloy of ninety 5 % copper and 5 % zinc to copper-plated zinc. Nickels are composed of an alloy containing seventy 5 % copper and 25 % nickel. because the Coinage Act of 1965, dimes, quarters, 0.5 money and dollar money are all clad money, made up of three coin strips that are bonded mutually and rolled to the mandatory thickness. The face of those money is seventy 5 % copper and 25 % nickel and the middle, it really is seen alongside the perimeters of the money, is composed of organic copper.
