<p>[QUOTE=&quot;GDJMSP, post: 1410488, member: 112&quot;]Mark - the US stopped using files to adjust the weight of planchets and coins around the same time that the steam powered press was introduced - in 1836. If you read the article you are talking about more closely I think you will see that they are talking about the process used prior to 1836. I have no doubt the letter was written in 1894, but the time period &amp; processes being discussed in the letter took place long before that.[/QUOTE]</p><p><br /></p>
