<p>[QUOTE="Conder101, post: 3642209, member: 66"]Clawcoins, those tonnage figures you listed are HUBBING tonnages, the maximum pressure used in the hubbing of the steel dies not the striking of the coins. Tonnage pressure for striking cents is around 40 tons.</p><p><br /></p><p>And the die life of a cent die is between 1 and 1.5 million strikes. Nickel dies on the other hand last 300 to 500 thousand strikes. The other denominations around 750,000 strikes. So a cent die lasts about 28 hrs, a nickel die about 9 hrs, and the other denominations about 17 hrs. So you swap out the cent die each day, the nickel die each shift and the other denominations every other shift.[/QUOTE]</p><p><br /></p>
