As a result, the doubling <u>will appear on every coin struck from that die</u>.&quot; 3rd paragraph</p><p><br /></p><p>&quot;On the other hand, there is mechanical doubling. This type of doubling, which is also known as strike, ejection, shelf or shift doubling, is not the result of the design on the die being doubled. Rather, this type of doubling occurs when the die strikes a planchet. If the die is not properly seated, it can move slightly or bounce during the moment of striking, creating a flat, shelf-like doubling. <u>This effect will be different on all coins struck, so it is technically not a variety, but rather more of a striking error.</u>&quot;&nbsp;&nbsp; 5th paragraph[/QUOTE]</p><p><br /></p>
