It'll rust away faster, but (assuming they're made from the same alloy) won't start to rust faster.
it will rust faster in vinegar
coke will make it rust faster
salt will rust the coin faster thanfresh water
vinger makes it rust faster because it has acied in it and tap water does not
water would make a nail rust faster because nails rust faster in water or any acidic liquads. As I been told
A nail will rust faster in wet soil than water, but if the soil is not wet , the nail will rust faster in water. I hope this answers your question. Bye, Annette Pfohl
Maybe. The question is ill-defined as written. If I take a metal object of known mass, and let it rust in such a way that none of the rust crumbles and falls off the object, the rusty object will indeed have a slightly greater mass than the original object did.

No. An object cannot rust unless it contains iron.
it rusts faster when it is damp cause the moisture of the damp and oxygen when they meet they create rust
i believe the nickel wil rust more faster in salt water do to the variety of minerals. Also it doesn't rust that fast do to corrision
Yes, it actually rust's faster than in normal water.
