<p>[QUOTE="GDJMSP, post: 2908605, member: 112"]The one dark line on the obv, as Jim said that might be the result of a rubber band being around the coin while it was in a 2x2 or flip. But everything else, in my opinion what we see is just what happens to circulated coins in the normal course of their lives. As a coin circulates it gets dirty, it accumulates dirt on it. All the oils transferred to the coin from fingers and hands, those oils attract dirt and make it stick to the coin. And any recess there is on the coin, whether that recess is a part of the design or from a contact mark, a scratch, whatever, the dirt and grime is pushed down into those recesses and it stays there. Of course the oils and dirt and grime also gets on the higher parts of the coin, but as the coin circulates that dirt on the high points get rubbed off, while all the dirt and grime in the recesses stays there because it's protected down in those recesses and nothing can rub it off.</p><p><br /></p><p>Look at the coin, all the recesses, all the contact marks, all the scratches, all the protected areas, every one of them shows dark. But all the high points don't. Simply put that's just what happens to coins as they circulate, it's completely normal.</p><p><br /></p><p>That said, you can also see a similar effect when a coin has been harshly cleaned.
