<p>[QUOTE=&quot;Marshall, post: 7609944, member: 21705&quot;]It still comes down to your believing the questions have been settled and if anyone doesn&#039;t agree with you, they are wrong. </p><p><br /></p><p>Maybe it&#039;s true and I&#039;m just not aware of how this consensus of experts came to this agreement. Was there an agreement after a huge convention of experts that I&#039;m not aware of? It sounded to me like you just left it in the hands of a TPGs to decide for everybody. </p><p><br /></p><p>Did all the major TPGs come to the same conclusion for the first time ever? And do you think those that have been disagreeing for decades are ignorant of the minting process? Hardly. These are ALL experts at some level in the causes of the issues called by different names.</p><p><br /></p><p>How do you spell color? If you spelled it like I did you would be wrong if you grew up in England and right if you grew up in the States.</p><p><br /></p><p>In my own view, it makes sense to aggregate all incused damage into the die into a greater heading. This would include chips, breaks and CUDs. I consider chips to be isolated and usually (but not always) smaller and shallower. But like on Obverse 19 of 1794, two or more chips can wear into a pretty substantial size. Another groups is the crack with both sides remaining close together and on the same surface plain. </p><p><br /></p><p>But there is also the group where one side breaks away from the crack leaving a wider raised mass. I usually see them as a crack passes close to a design detail like lettering or leaves or the reverse fraction. This group name seems to be the bone of contention. Is it a greater crack or a differently located CUD?</p><p><br /></p><p>If the above happens at the rim, there is fairly wide agreement that it is a CUD or Full CUD. But is that the universal set or merely a subset?</p><p><br /></p><p>Now there is a subset called variously a developing CUD or incomplete CUD because while the levels are changing, it has not yet obliterated the design detail or become solid.</p><p><br /></p><p>Most people know what is happening, but just group them differently. To say a group that disagrees is wrong is like saying the ENGLISH are spelling color wrong.[/QUOTE]</p><p><br /></p>
