Because coins don't rust at all the last know coin was found a really long time ago. Also that coin don't have the certain needs that allows them to rust.
Yes they will.
Modern coins cannot rust, as they are not made of iron.
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Salt
salt water cause of the salt particals in the water
A nail would probably rust faster in fresh water because rusting, also called oxidation occurs when large amounts of oxygen are forced into the metals pores, causing it to turn brittle.
It depends on the coin, however most will not as generally most coins do not contain iron (or steel). coins made from copper or tin will not rust ever.
A penny will rust faster because it made entirely of zinc with a thin outer coating of copper, and zinc is made to rust unlike nickel which is used to make nickels, dimes, etc...
