<p>[QUOTE=&quot;johnmilton, post: 7835515, member: 101855&quot;]The thing you need to do is to be able to spot mint luster. You need to be able to distinguish mint luster from cleaned surfaces. That is not easy, especially for an inexperienced collector. </p><p><br /></p><p>When a coin is stuck, under many tons of pressure, the metal flows like a liquid. The finished coin has surfaces that play with the light, which is often called &quot;cartwheel luster.&quot; When you swirl a Mint State coin under a light, you can see it. If there is a break in the luster, the coin is not Mint State. If there are dull spots (&quot;duller gray&quot;) on the design devices, it is probably a rub. </p><p><br /></p><p>This is how you learn to distinguish between wear and a weak strike. It is not the easiest skill to learn, but it is very valuable. And sadly, some people never get the hang of it.[/QUOTE]</p><p><br /></p>
