Coins are typically made of metal, such as copper or nickel, which can react with oxygen in the air to form rust. When coins are exposed to moisture, especially salt water or acidic substances, this can accelerate the rusting process. Over time, this chemical reaction can cause the surface of the coin to corrode and develop a reddish-brown appearance.
