Sometimes only the mintmark will show the machine doubling. Basically the die is chattering against the coin, and the die will shift a little bit. This &quot;scrapes&quot; the design to create the flat, shelf-like appearance you see. It is quite common for this to only happen on a small part of the coin.[/QUOTE]</p><p><br /></p>
