<p>[QUOTE=&quot;mikediamond, post: 951141, member: 1859&quot;]If it is a dropped letter then it&#039;s the first legitimate example I&#039;ve seen on the edge of any dollar coin.&nbsp; But such an error is possible since the Schuler press has horizontally oriented dies and therefore has a vertically oriented collar.&nbsp; That means that a few arc degrees of the working face of the collar faces directly upward and can function as a resting place for a dropped filling.&nbsp; Has Ken Potter mentioned what characteristics persuaded him it&#039;s a dropped letter instead of a contact mark from the &quot;T&quot; in PRESIDENT?&nbsp; I&#039;ve read the article and he presented no observations or argument that would advance his hypothesis.&nbsp; So I remain non-committal.&nbsp; Here is the full link:</p><p><br /></p><p><a href="http://www.numismaster.com/ta/numis/Article.jsp?ad=article&amp;ArticleId=12295" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.numismaster.com/ta/numis/Article.jsp?ad=article&amp;ArticleId=12295" rel="nofollow">http://www.numismaster.com/ta/numis/Article.jsp?ad=article&amp;ArticleId=12295</a></p><p><br /></p><p>If this is a dropped letter, then its appearance would have preceded the impression of the incuse edge lettering.&nbsp; If it&#039;s a contact mark, then it could have appeared before or after the edge lettering was applied.&nbsp; If it&#039;s a contact mark that appeared after the edge lettering was applied, then we might be able to detect some microscopic indication of this.&nbsp; If there is a microscopic pressure ridge surrounding the incuse letter, then it would be a contact mark.&nbsp; Lack of a pressure ridge would not necessarily invalidate that conclusion but would simply bring us back to a state of uncertainty.[/QUOTE]</p><p><br /></p>
