<p>[QUOTE=&quot;Conder101, post: 958625, member: 66&quot;]Boulton and Watt processed the copper but they didn&#039;t do the smelting and refining of the copper. It may be a change or improvement had been made in the refining process by the producers, I don&#039;t know.&nbsp; I have never heard of any special request made by Patterson for an improvement of the purity.&nbsp; (The copper in the draped bust coins was already in the 99% pure range.)&nbsp; Do you know where I can find a copy of that request?&nbsp; I find nothing in the annual reports made to the President or Congress.[/QUOTE]</p><p><br /></p>
