There are some tools/weapons known to have been worked from copper ore by North American Indians.
I think that Otzi's axe was fairly pure copper, wasn't it? |
A lot of the early copper work was fairly pure copper (such as axes, battle axes, daggers etc.). Later copper with natural impurities such as arsenic became more common, and they may even have added arsenic or antimony themselves.

Pennies are mostly nickel with a copper plating now since copper is so expensive. Even so, I've heard that they are are now worth much more than 1-cent now. |
I thought that only applies to the ones made from mostly copper, before they switched over sometime in the '80s.
