Judging from this post on the first page it will be a complete waste of time with lots of "misinformed opinions" that will only confuse folks who read it. At first I would ROTFL and then become very angry at the state of numismatic education in this country. Perhaps Doug had a different way of defining an MS years ago to make a point after I stopped reading.</p><p><br /></p><p><font size="6"><b>Fact: An as struck coin is 100% mint state when it leaves the dies.</b></font> Learn it.</p><p><br /></p><p>There is a very simple way to confirm the actual direction of metal flow that can be done at any facility with a die and a press. Prepare a planchet and paint colored rings 1mm wide From the rim inward for 1cm. then strike the planchet and see where the colors end up. An aluminum planchet with anodized colored rings should work even better. This would make a valuable addition to the story of the minting process.[/QUOTE]</p><p><br /></p>
