I found this copper disc lying in my washing machine.

It is an old penny, by the evidence on the other side.

The year is completely worn off, as is Lincoln’s face, but the fact that it is still copper colored and not silvery zinc tells me (according to the internet) that is was made before pennies were only copper plated, around 1982.

I think it was stuck in my washer until it was worn thin enough to escape. I’m keeping it because the wear pattern looks like a tree and roots, very similar to my graphic design logo.
