The question does not make sense because copper is a metal.

A 1983 Lincoln cent is actually copper plated zinc, 1982 was the last year for copper pennies. It's just a penny.

Copper is one of the most malleable substances. An example of how malleable copper is is the penny, which is made out of it. And pennies last almost forever x

US Coins the last year for a copper (actually bronze) penny is 1982. In 1982 the penny was made as a copper coin and a copper plated zinc coin. You have to weigh them to tell the difference. Bronze cents weigh 3.11 gm and zinc ones weigh 2.5 gm. The penny has remained a copper plated zinc since 1982 however there is talk of changing it again to a copper plated steel coin. In 1943 the Lincoln US cent was steel coated with zinc because the copper was needed for ammunition during the War. In 1944 it went back the copper coin. Today the cost of copper is too high to make a solid copper coin/penny. In fact the cost of stamping/minting the coins and raw materials, the penny and nickel cost more to produce than their face value.

The copper content of a penny was changed because the old copper substance made people have skin irritations and rashes. The new penny does not do that.

You can tell if a penny is made out of zinc or copper by the date on the penny. If the date is before 1982 then the penny is 95% copper. Pennies dated 1983 or later are 97.5% zinc with a thin copper coating.

zinc is 97.5% of the penny and copper is 2.5% of the penny

did they make 1982 copper penny by mistake

Copper reacts with the oxidilized copper on the penny.

1982 was the last year for 95%-copper pennies. And the first year for the zinc pennies. They made both types that year, and the only way to tell them apart is by weight -- the zinc pennies are lighter.Answer100% copper pennies were last minted by the US in 1857. These were large cents, about the size of the "golden" dollar coins. The Flying Eagle and Indian Cents from 1856 to 1864 were 88% copper and 12% nickel. Beginning in 1864 Indian Cents, and later Lincoln Cents, were minted in 95% copper and 5% tin, technically this is bronze. AnswerAnother way to tell the copper penny from the copper coated zinc penny is when a penny is dropped on a hard surface the copper penny will have a ringing sound, the zinc penny will not ring.

No, copper and zinc are not magnetic.

The penny is made out of copper.

A copper penny turns green due to oxidation. When oxygen combines with copper, it produces copper oxide, which is green, in color.

Those are 95 percent copper. A US penny weighs 3.11 grams. Of that, 2.9545 grams is copper.

The penny has copper in it. Copper reacts to the oxygen in the air by producing copper oxide therefore turning green. The older the coin, the more copper in the coin.

Convert copper molecules into copper oxide molecules (copper and oxygen).

The US penny, the symbol for one cent, is not brown... but copper. Yes, the penny is made out of copper. Copper was a very economical metal back then when it was starting to be made. However, for a short period of time, while I believe during the WW2, the penny was made out of something else, other than copper for a few years and then went back to being made out of strong copper. That is why quarters, dimes, nickels, and other coins always need to be remade, and that's why pennies are stronger and can last longer... because of the strongness of a penny. Even though it's worthless, it's pretty unworthless. Also, when copper is first exposed to air, it oxidises very quickly. Then, the common oxide of copper is brown... that's why the color of copper is brown. And therefore, the penny is brown.

In 1943 the US Mint briefly replaced the copper penny then in use with a steel penny, due to the wartime copper shortage.
