I posted this penny awhile back and i did not have photos. So here are two photo both 1970 S minted pennies. The one on the right has the green tone. Is this normal and dose it have any value ?
Absolutely no added value. Just toning and/or environmental effects. I'd throw it in a fountain; you'd get a free wish out of it, then! Keep an eye out, though, some of the errors on lincoln cents can be rare and valuable. Hope this helps!
