But yet it is one of the most often repeated ideas there is in numismatics.</p><p><br /></p><p>Start with why planchets are run through the upset mill. That is done to make sure there is enough metal to form the rim of the coin when the planchet is struck. And it is specifically done because the people at the mint know for a fact that when a coin is struck the vast majority of the metal flows inwards towards the center of the coin - not outwards towards the rim !</p><p><br /></p><p>On almost all coins the single largest part of the die that must be filled is the central device, in the center of the coin. And that is where the vast majority of the metal flows to - to fill that portion of the die.&quot;[/QUOTE]</p><p><br /></p>
