<p>[QUOTE=&quot;TOKENHUNTER, post: 1952468, member: 37910&quot;]I appreciate the clarification regarding differences in color by those who have experience in this matter. I clean coins with a 50/50 mix of alcohol and water, a lot of elbow grease and a soft cotton cloth.</p><p><br /></p><p>After finding and inspecting the Krugerrand that I posted about, I have come to the conclusion that the difference is more about lustre, not really color. These pics are from phone. Without controlled lighting I don&#039;t know if you can see what I mean.</p><p><br /></p><p>These two coins, viewed in person, look pretty different. The 1974 (left) is typical of color and finish. The 1978 on the right is noticeably brighter, shinier, and therefore appears a slightly different color.&nbsp; The 1978 brighter coin even appears to be smoother under magnification, in the sections where the metal is cast against a non-etched section of the mold.&nbsp; The typical Krugerrand appears to have a natural &quot;grain&quot; to the metal, like fine sand, where the bright coin has much less.</p><p><br /></p><p>The difference is more about shininess, like what you would expect between a proof and a non-proof. So I am wondering if the coin that appears brighter is either a special run, or possibly struck w/a brand new die?</p><p><br /></p><p>It is such a stark difference to observe under bright lights. Apologies if you cannot see it here.[/QUOTE]</p><p><br /></p>
