<p>[QUOTE=&quot;coop, post: 1085528, member: 17656&quot;]Machine doubling can be selective. It can affect one letter/area/side or just the mint mark. It just depends on how the twist/movment of the dies affect the coin made. The dies are normal, just the striking was distorted. On a doubled die, the doubling is caused because it is on the die, not happening during the striking. Az shown here on several coins with the same die pair with the same die movement with different parts affected:</p><p><img src="http://imgs.inkfrog.com/pix/coop49/Machine_Doubling_Different_from_Coin_To_Coin.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
