The planchet is trapped betwen these 3 things. And when force is applied to the planchet in that confined space, the planchet is squished, compressed. And when it is compressed the pressure increases because it cannot escape. The metal cannot flow beyond the confined space so the pressure inside that space increases. It can do nothing else.</p><p><br /></p><p>But apply that same amount of force to the planchet when it is not in a confined space, which it cannot be if it is an off center strike because the collar is not there confining it, and the pressure only reaches a fraction of what it does when there is a confined space. And with reduced pressure, the coin cannot be fully struck.[/QUOTE]</p><p><br /></p>
