Silver (coins) do NOT rust.
Rust the iron when oxidised.
Silver will oxidise very slowly, to form silver oxide, which is black in colour, This oxidation process can take weeks/months to occur.
If you have any silverware, you will normally polish it once a week. this prevents oxidiation. However, if you leave it unpolished for say , 6 months, the silver will appear dull or black in places; this is silver oxide.

Yes, gold and silver are at the bottom of the reactivity chart and therefore less likely to rust when in contact with water.

This is why we do not use iron, which is cheap and durable, to make coins almost anytime in history.

How can a coin rust?
Coins are typically made of metal, such as copper or nickel, which can react with oxygen in the air to form rust.

Over time, this chemical reaction can cause the surface of the coin to corrode and develop a reddish-brown appearance.
