What are the requirements for a coinage metal?
Requirements for a coinage metal Coins that are intended for circulation have some special requirements based on the conditions they will encounter. For example, a coin may be in circulation for up to 30 years, and so must have excellent wear resistance and anti- corrosion properties. Achieving this goal necessitates the use of base metal alloys.
Why are coins made of copper silver and gold?
Copper, Silver, and Gold are the elements you’re referring to. The reason these metals are used in traditional coinage is due to their relative abundance compared to other metals. However, coins were also made from other relatively common metals such as iron, or bronze, which is a copper alloy with Tin, or sometimes Zinc, Aluminum or Nickel:
