Copper is an interesting metal. It’s fairly common, so it’s used in many ways, from currency to electronics. It’s also an element I never give much thought to, except to recall that when it oxidizes, you get the greenish color.
I just recalled that it’s also one of the words in the English language that can refer to a police officer, although it’s not one I hear often, being an American. I do read some literature, so that’s the last place I recall seeing it.
All this talk of copper got me thinking about pennies, so here’s a couple of sayings I’m aware of:

Find a penny, pick it up, and all the day you’ll have good luck.


A penny saved is a penny earned.

–Benjamin Franklin
