  2. Coinage metals - Wikipedia

    en.wikipedia.org/wiki/Coinage_metals

    Historically, most coinage metals are from the three nonradioactive members of group 11 of the periodic table: copper, silver and gold. Copper is usually augmented with tin or other metals to form bronze. Gold, silver and bronze or copper were the principal coinage metals of the ancient world, the medieval period and into the late modern period ...
