Because salt water has codium to make rust.
Salt Water!
Salty water will rust metal the fastest because the presence of salt increases the rate of oxidation, which leads to rust formation. Cold water alone does not promote rusting, but when combined with salt, the process is accelerated.
Distilled water will rust a nail faster as distilled water contains higher levels of OXYGEN which is what causes OXIDATION or commonly referred to as rust...

warm water will rust metal faster
salt will rust the coin faster thanfresh water
Salt Water Because They Rust In Normal Water Too!
Sea water can rust nails or other metals.
Salt water
Objects will rust more quickly in salt water due to the corrosive nature of salt, which accelerates the rusting process. Objects made of stainless steel, aluminum, or plastic will not rust at all due to their resistance to corrosion.
