It depends on what metals the coin is made from!
two weeks
Most likely salt water. The salt accelerates the rate of corrosion, plus it has the oxygen needed for the metal to rust. Tap water has the oxygen too but with the salt also, it would cause the metal to rust more rapidly.
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
salt in the name given to the metals that react in water, so if there is salt in water and it goes through a metal pipe for example, if the metal reacts with water it is going to casue rust.
It will most probably rust first in salt water, I wanted to rust a chain so that i could keep it in the shape of an eight, so i soaked it in salty water for a day or two
the wool does not rust
salt will rust the coin faster thanfresh water
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.
Because salt water has codium to make rust.
will objects rust more quickly in salt water or plain water without salt
Salt Water Because They Rust In Normal Water Too!
salt water would rust a nail in roughly 2 hours as salt has a fast reaction to metals (nails).

Metal rust quickly in salt water than it does in pure water.
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
