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.
