Metals are exposed to the atmosphere and corrosive environments such as the sweat on the palms of hands. As coins are designed to be around for a long time (unlike banknotes) the metals they are made from need to be a of very low reactivity so they do not corrode.

What are the alkali metals and coinage metals?
Alkali metals are group 1 metals such as lithium, sodium, potassium, rubidium, cesium and francium. Coinage metals are metals used in coin age to make coins. They are copper, gold and silver.
What are the properties that make metals suitable for coins?
Almost any metal is suitable for coins. But from a practical point of view, metals should be fairly hard, so that the imprint doesn't fade too quickly and it shouldn't be too light since most people like their coins to have a little 'weight', certainly if a coin represents a certain value.
What transition elements are considered to be coinage metals?
Copper, Silver and Gold are the traditional "coinage metals". However many modern coins around the world contain nickel because it's relatively inexpensive and very resistant to wear. Low denomination coins are often made of plated steel or zinc, while brass alloys are used to give higher-denomination coins a golden appearance.
Why does copper silver and gold occur as deposits?
because these metals are used to make coins.
How the elements in the iron triad differ from the other transition elements?
According to the eighth grade Physical Science textbook, the reason that they differ is because the coinage metals are arranged the way they are so stable and malleable and can be found as free elements in nature. These metals were used widely to make coins, giving them the title of the coinage metals. As for the iron triad, it differs because the elements are used in the process to create steel and other metal mixtures.
