<p>[QUOTE=&quot;non_cents, post: 1699911, member: 30970&quot;]Your description of how machine doubling occurs is incorrect. What you are referring to would be known as a double struck coin.</p><p>Machine doubling occurs as the coin is struck. As the die descends on the coin leaving the first strike, it bounces up ever so slightly and lands down lightly enough to flatten part of the design, but not strongly enough to leave a second strike.</p><p>The coin pictured in this thread appears to have push-plating doubling and offset die wear. Here is a tutorial thread I have done on different types of doubling. <a href="http://www.cointalk.com/t224087/" class="internalLink ProxyLink" data-proxy-href="http://www.cointalk.com/t224087/">http://www.cointalk.com/t224087/</a></p><p>Keep up the hunt![/QUOTE]</p><p><br /></p>
