<p>[QUOTE="mikem2000, post: 1543484, member: 30574"]But of course, and this is where it gets tricky. Bag marks are WEAR. They are caused by FRICTION, just like any other wear. When two coins strike, the friction either moves or displaces the metal. It is wear. it is just not wear caused by circulation. Just shake those bags of Morgans around for 1000 years or so and they will WEAR down to nothing. The other difference is bag marks are easily recognized. The reason for this is the characteristics of silver. Basically it is hard. When Morgans contact each other, they tend to scrape and slide.</p><p><br /></p><p>Now gold is different, since it is much softer, the friction that is caused when two coins rub, more closely resembles wear that is caused by general circulation. It is the same process that caused the wear in the Morgans, but it looks different and more difficult to tell the difference between those contact marks and circulation friction. So the question would be, do the Saints get penalized from making it into an MS holder, just because the metal is softer, and contact marks show up differently?[/QUOTE]</p><p><br /></p>
