I' still trying to learn here, and even though this isn't my post or coin, it's the comments a few of you have made about it being and old cleaning. I'm pretty sure of myself when it comes to buffing, whizzing, scrubbing, spot cleaning, even too long a dipping, but it's the old cleaning I don't understand. Is it the the dark around the stars? If not that, then what tells you it's an old cleaning?
