<p>[QUOTE=&quot;CoinMagic, post: 24660421, member: 148457&quot;][USER=10461]@lordmarcovan[/USER], your detailed explanation of luster effects:&nbsp; <b>When that metal is distributed differently across a coin’s surface (by being struck into distinctly different designs), you get different reflections of the light and therefore different luster patterns. </b>has hit home for me in understanding much more clearly the &quot;what&quot; of the impact the flow lines has on the luster aspect.</p><p><br /></p><p>While I was utterly fascinated with physics fan&#039;s various scientific explanations on the chemical composition of the die strike&#039;s impact on the coin&#039;s surface, it seemed not really fully address the &quot;what&quot; of the luster&#039;s shine on particular coins.&nbsp; Based on what you&#039;ve described, lordmarcovan, it seems to come down to the coin&#039;s specific design that impacts the flow lines and luster level.&nbsp; How I envisioned this particular process in my mind is a bunch of nano-sized liquid silver pebbles scattering all across the planchet&#039;s surface and going &quot;bump&quot; over the design elements such as rays, head, arrows, etc. that affects their flow lines&#039; direction on both the obverse and reverse sides for circulated coins.</p><p><br /></p><p>[USER=15199]@desertgem[/USER] I visited both the U.S. Mint and Royal Mint websites to study their Proof coins and commemorative coins.&nbsp; One can clearly see that their luster surfaces and alloy composition impacts the price levels for each coin.&nbsp; The Star Wars coin is so cool that I was highly tempted to buy it.&nbsp; But need to remind myself &quot;patience is a virtue&quot; when it comes to taking the plunge as a coin buyer.&nbsp; So, lordmarcovan, I&#039;ll be staying away from your giveaways at this time.&nbsp; Thanks for the kind offer![/QUOTE]</p><p><br /></p>
