If you don&#039;t get things PERFECTLY aligned for the two, you double the die.</p><p><br /></p><p>The signs of this are either &quot;split serifs&quot; (e.g. the fancy corners on letters show visible separation) or sometimes fattening (on sans serif design elements).</p><p><br /></p><p>&quot;Mechanical doubling&quot; or &quot;Machine Doubling&quot; happens on an individual strike when the planchet bounces a bit and the sign of that is a flat shelf as part of the &quot;doubling&quot;</p><p><br /></p><p>There are also doublings that occur when the dies are worn.</p><p><br /></p><p>Visit <a href="https://www.error-ref.com/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.error-ref.com/" rel="nofollow">https://www.error-ref.com/</a> for much more information.[/QUOTE]</p><p><br /></p>
