<p>[QUOTE=&quot;desertgem, post: 3006430, member: 15199&quot;]Jeff I have read sunnywood&#039;s posts as well, and I do think <b>I</b> left a lot of meat between the skin and the bone and I apologize. I didn&#039;t mention the interference of the two surfaces to produce the coloration seen and I agree with his hypothesis, but it doesn&#039;t explain why the Peace dollar toning typically is much flatter in visual appearance than the toning on a Morgan even exposed to the same environment and that was what I was trying to explain. On the coin flow lines? ( what else to call them) all of the inclined (side)surfaces have the film interference as well as any microscopic base areas, so my thought is that since they are probably of different angles and altitudes on the surface, the light ( color) from a relatively smoother surface would allow the color to stay more coherent than the color from the more incoherent Morgan surface with higher semi-random ridges on the surface. We are seeing the tone with our eyes/brain which throws in a wild card as to how the brain uses the variations to see a color as flat or as sparkling ( flat paint/glossy paint) even though the same wavelength of light interference (color wise) is there, the base matrix of the paint of course causes most of that, I suspect. Sorry for the rambling. Jim[/QUOTE]</p><p><br /></p>
