Your coin has great colors, but the lack of a pattern on your coin is more the point here. On the first coin, there is a locus - the center has the purples, then it clearly fades to the blues, then greens, then yellows. It&#039;s not the crescent arc that we are most familiar with, but there is a clear and distinct color progression across the coin. </p><p><br /></p><p>Your coin has that great natural color progression, but the colors are more intermixed. Again, completely natural and fantastic shades of color, but it isn&#039;t the smooth transition of the first coin. </p><p><br /></p><p>Ahh, I&#039;m not explaining it well. It&#039;s more of an intuitive thing, but my impression is the first coin has a more pleasing transition than yours does.[/QUOTE]</p><p><br /></p>
