<p>[QUOTE=&quot;rlm&#039;s cents, post: 1770117, member: 7957&quot;]You are confusing the daylight out of me.&nbsp; First off, all the coin you see was the same &quot;level&quot; on the original planchet - the top surface.&nbsp; The minting process does not machine into the planchet and I am sure you understand all of this.&nbsp; So just what are you referring to with your &quot;levels&quot;?</p><p>&nbsp;</p><p>On the other hand, I have always been convinced that the differences in color appear due to toning (i.e. oxidation).&nbsp; Doug seems to feel that the color difference is present from the get go.&nbsp; Maybe you have managed to show that he is wrong.&nbsp; Probably the last area on a Lincoln to turn brown is that area between the rim and the bust.&nbsp; In other words, it is the last area to tone.&nbsp; Therefore, it would be the last area to show the grain.[/QUOTE]</p><p><br /></p>
