Coinage metals

Coinage metals are a group of precious metals—copper, silver, and gold—that have historically been used to produce coins due to their durability, malleability, and attractive appearance. Copper is widely used in coins because it's readily available and resistant to corrosion. Silver has been valued for its luster and conductivity, while gold is highly resistant to tarnish and has long been associated with wealth. These metals are part of a specific chemical group called the "coinage metals" because of their traditional role in currency and easy workability, making them ideal for minting coins and other decorative applications.
