Coinage metals are metals that are primarily used to produce coins. The most common coinage metals include copper, silver, and gold. These metals are chosen for their durability, resistance to corrosion, and ability to be easily shaped into coins. Historically, coinage metals have also held intrinsic value, making them suitable for trade and commerce. The use of these metals in coins dates back to ancient civilizations, where they were minted to facilitate economic transactions and establish a standard of value. Today, while many coins are made from less valuable alloys, silver and gold coins are still produced for collectors and investors.
