1930-D is much better than 1930. 40 million as opposed to 157 million minted. Condition is a little circulated, but I would keep it. Nice find.
Indeed. Despite a little rim nick and some surface issues, that's a nice find. Give it a gentle rub with Vaseline and it'll look better. That will remove some of the loose surface grime without changing the natural coloration of the coin.
Nice find! Cents with MMs earlier than the 40s have become very difficult to find in circulation, especially on the east coast.
