Can a dime rust?
Actually, none of the coins will “rust”, because rust is iron oxide, the corrosion product of iron and steel, and none of your coins are iron or steel. Dimes can’t rust (they’re not iron or steel), but they can corrode or at least tarnish, but they probably won’t very much in 2 weeks.

Why does my dime look like copper?
How the Copper Dime Appeared. Dimes are made primarily of copper, and are coated with a mixture of copper and nickel to give the coin the appearance of a shiny silver surface. When the copper-nickel mixture wears off, the coin exposes its copper under layer, thus the brownish color of its surface.
What makes a dime turn black?
Toning occurs naturally over time. It is mostly the result of oxygen and/or sulfur reacting with the coin’s metal. Additionally, toning can also turn ugly and occur in shades of black and brown. In the most severe cases, the toning can turn into corrosion and cause permanent damage to the surface of the coin.
