<p>[QUOTE=&quot;GDJMSP, post: 1444540, member: 112&quot;]Detecto, I want to make sure you understand something. There is not one tiny speck of luster on that quarter. Not one. What you are seeing is not luster.</p><p><br /></p><p>Now for you to understand this completely and see it with your own eyes, do this experiment. Get yourself a brand new unc coin. Doesn&#039;t matter what it is, any unc coin will do and you can get it from pocket change.</p><p><br /></p><p>When you get the coin, get your Tarn-X back out, put about a half inch in the bottom of a bowl. Take that unc coin and hold it upright, and just dip the bottom half of the coin in the Tarn-X. Dipping it for 2 seconds will be long enough. Then go rinse it off and then look at it. </p><p><br /></p><p>What you will see is where the Tarn-X destroyed the luster on the unc coin. It will completely remove all of the original mint luster. You&#039;ll see a line right across the coin, the upper undipped portion will still have luster, and the bottom dipped portion will not have luster.</p><p><br /></p><p>The reason this happens is because Tarn-X literally eats away the top layer of the coin, and it is this layer, and only this layer, that has the luster.</p><p><br /></p><p>You can do the same test with a cloth and an unc coin. Rub the top or bottom half of an unc coin with a cloth, any cloth. then hold the coin up and look at it. Where you rubbed it, the luster will be gone. and you will the same kind of line, just not as distinct of a line, as you see with the Tarn-X</p><p><br /></p><p>Doing these things will help you understand luster and how to know it when you see it. And how to know when you don&#039;t see it. Understanding luster and being able to recognize it when it is there, and when it is not there, or even when there is just a break in the luster, this is the very foundation of learning how to grade coins. Well, unc coins anyway.</p><p><br /></p><p>Do these things, it will help you.[/QUOTE]</p><p><br /></p>
