<p>[QUOTE=&quot;Insider, post: 2714020, member: 24314&quot;]This is an age thing Mike...They don&#039;t do any of that anymore.&nbsp; Now the strip comes from outside vender in huge coils ready to go to blanking machine.&nbsp; For all I know, they get the blanks already made from the outside now! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie10" alt=":oops:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie12" alt="o_O" unselectable="on" unselectable="on" />&nbsp; <b>NOTE</b>: DO NOT TAKE THAT AS GOSPEL as I stopped caring how coins were made after the 1980&#039;s. I&#039;ll need to check.</p><p><br /></p><p>I cannot remember when the Mint stopped rolling ingots into strip in house.&nbsp; Probably in the 1970&#039;s as if I remember, I saw the mills - still hot - but not processing (rolling strip) at the time.</p><p><br /></p><p><br /></p><p><br /></p><p>I still want to understand that too.&nbsp; I thought the streaks were caused because the &quot;pour&quot; was not homogeneous - an &quot;Improper alloy mix.&quot; Any stretching from rolling would just elongate (pull) the different color metals out.</p><p><br /></p><p>Furthermore think of the problem of picking up a hot, heavy five foot long lump of rolled metal an carrying it around to pass thru again. Later the same operation would need to be done to a hot twenty foot long strip.&nbsp; Later, the strip would be 100&#039; long, etc. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie50" alt=":happy:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
