The following is an excerpt from the site:
"A reddish-gold metal that is easily worked and drawn into wire. It has
great ability to conduct both heat and electricity. Traditionally it has
been one of the coinage metals along with silver and gold, but it is the
most common and therefore the least valued of this group. Historically,
copper was the first metal to be worked by people and the discovery that it
could be hardened with a little tin to form the alloy bronze gave its name
to the Bronze Age. The metal is an essential element for humans."
