<p>[QUOTE=&quot;19Lyds, post: 1622687, member: 15929&quot;]What I &quot;see&quot; in the video, is a rotating drum with thousands of coins stacked on top of each other in a softened state, making contact with each other, at the end of the annealing process just before they enter the quench tank.</p><p><br /></p><p>What I do not see is a converyor belt with coins laying flat upon it and not touching each other as they pass through an annealing oven. I see a piece of equipment labeled &quot;Furnace #5&quot; which is in close proximity to a stair case that does not appear to have the length required to pass thousands of blanks through it laying flat on a conveyor belt which in my minds eye would be hundreds of feet long.</p><p><br /></p><p>[ATTACH]230683.vB[/ATTACH]</p><p><br /></p><p>As for thinking about it in conjunction with the first link that was presented which states &quot;(use temperature between 300-600 degree Celsius for 30 minute)&quot;, I just cannot see a flat conveyor that would be that long. For limited production proof coins, perhaps, but I just do not see it with blanks that were produced in the hundreds of thousands for circulation. Maybe its a control station? I don&#039;t know.</p><p><br /></p><p>I forgot to add, I don;t think that Doug is wrong but I do believe that there are different processes for circulation coins vs proof coins with proof coins receiving special handling which just may include flat annealing.[/QUOTE]</p><p><br /></p>
