I'm no coin collector, but I've never seen a silver penny before, have you?
This is a 1943 penny. Wait. What? Aren't most pennies made of copper? Yes, most are. However, 1943 pennies (also known as a silver pennies, because they look as though they're made from silver, as seen in the picture above) were made of steel, because the U.S. was elbow deep into World War II and copper supplies were scarce. What's interesting, is that silver pennies are actually more common than these 1943 copper pennies, seen here:
These particular copper pennies are rare. They're collector's items.
As a writer, I want to be a 1943 copper penny. Of course I want to be a rare treasure amongst all the other common pennies out there. But the depth of it? Copper is more malleable than steel - hot or cold, it has a greater ability to be bent and shaped without cracking. It's unique because of what it's made of.
I want to bend easily - to be capable of being shaped without cracking. I don't think I'm there yet, but hopefully someday.
