What percent copper is a 1984 penny?

Next to none. Post-1982 pennies are only plated with copper, they are mostly zinc. The amount of copper on a post-1982 penny is miniscule and costs more to remove than melt value is.


How much is a 1963 copper penny worth?

1963 COPPER penny is worth half a billion dollars.


Why did the composition in pennies change between 1981 and 1982?

because in 1982 there was a war going on and copper was short and they needed copper for their weapons so they stoped using copper for the so called "penny" and used zinc instead but they still used a copper collered coating. :) hope this helped because in 1982 there was a war going on and copper was short and they needed copper for their weapons so they stoped using copper for the so called "penny" and used zinc instead but they still used a copper collered coating. :) hope this helped

Why is the penny brown?

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.
