That die will strike 1,000,000 or more in its life. Unless there is a significant catastrophic event, 10 coins is nothing in the life of this die!</p><p><br /></p><p>If you were fortunate enough to get individual coins thousands of strikes apart, you could probable trace the growth of the crack. Early US coin collectors do exactly this sort of die study - they&#039;ll bring dozens and dozens of examples of known die varieties to a meeting and compare little differences in die cracks, figuring out exactly how it progressed.</p><p><br /></p><p>For something like a dozen found in a roll, however, I&#039;d expect every single one to appear exactly the same unless you&#039;re using an electron microscope![/QUOTE]</p><p><br /></p>
