How do you tarnish pennys?

Answer 1

Tarnish (AKA toning) is caused by exposure to air, chemicals, and/or dirt & oils from human fingers. A chemical reaction causes oxidation of the metal and the change in color. The same thing happens to silver coins. OMG

Answer 2

To tarnish pennies, you can expose them to acidic substances like vinegar or lemon juice, or use a commercial tarnishing solution. Place the pennies in the solution for a few hours or overnight until they achieve the desired level of tarnish, then rinse them with water and dry thoroughly. You can also try rubbing the pennies with a mixture of salt and vinegar.

Answer 3

Vinegar is an acid, so it can break stuff down really good, therefore cleaning the penny when it is dipped into the vinegar

but can you explain it more

you can do this with multiple pennies at a time, it's just that you can't just dip it in. you have to leave it in for a certain amount of time. this does work. the answer is as simple as vinegar is an acid. acid pretty much brush off all of the rust.

Answer 4

This caused by oxidization of the coins' surface.

US and Canadian cents, and British pennies, were once made of copper or a bronze alloy that was mostly copper. Today they're made of other metals (steel or zinc) but are plated with copper so they look the same as their older bronze / copper versions. Copper turns brown when exposed to oxygen and pollutants such as skin oils and dirt.

Answer 5

Because many people drop pennies on the ground and who knows what else the penny touches.

Answer 6

Because people drop them and put them in waterfountains and they have been used for a long time probably :)

Answer 7

corroding is created when iron and oxygen mix. So pennies corrode because they get oxidized too much. And they can't handle it anymore.

Answer 8

Damp conditions tarnish copper and bronze pennies quickly. Bleach can also tarnish them.

Answer 9

the oxygen in the air
