Is There Any Value In An Unmarked Copper Penny? No Markings At All!

I have a faceless penny no stamp on back are face

One use for a copper slug is that collectors of elongated coins like to use them instead of hunting down and cleaning pre 1982 pennies.

This is what's known as a slug. They're used for vending machines and they're illegal. Usually they are something larger and more worthwhile - like a quarter, which makes more sense. I don't know why anyone would bother to make a slug of a penny.
