<p>[QUOTE=&quot;Insider, post: 2551297, member: 24314&quot;]This thread provides a really good example from a grading seminar I was in.&nbsp; The following is an opinion.&nbsp; No attacks on members are to be implied.</p><p><br /></p><p>[USER=73165]@Paul M.[/USER] posted: &quot;Tilt the coin <span style="color: rgb(0, 89, 179)">[back and forth while you rotate it at the same time</span>] under a strong light [<span style="color: rgb(0, 89, 179)">75w-100w in a dark room</span>] and look for hairlines going in roughly the same direction.&quot; <span style="color: rgb(0, 89, 179)">When this is not done, you me, and the TPGS may miss the cleaning.</span> &quot;Based on this image, the problem area might be the obverse around the olive branch.&quot; <span style="color: rgb(0, 89, 179)"> Note the dark patch.&nbsp; This is possibly the place the light buffing &quot;ate&quot; too far into the coin&#039;s surface.</span> <span style="color: rgb(0, 89, 179)"> Light cleaning that leaves the entire surface covered with parallel hairlines is the main reason that beautiful coins like this are down graded to &quot;details&quot; or MS-61.&nbsp; </span>Or, it&#039;s possible PCGS made a mistake.&nbsp; It happens.&quot; <span style="color: rgb(0, 89, 179)">Yes, the TPGS make mistakes but <span style="color: rgb(255, 0, 0)">NOT</span> in these situations.&nbsp; TPGS wish to grade coins as high as they can.&nbsp; &quot;Straight&quot; grades sell.&nbsp; It makes everyone happy.&nbsp; If they &quot;detail&quot; a coin, it is an extremely rare occurrence that it was a mistake.&nbsp; The &quot;sniffer&quot; is for chemical alterations, not mechanical alterations such as cleaning. </span></p><p><br /></p><p>[USER=43130]@C-B-D[/USER] posted: &quot;To me the coin&#039;s fields show no [<span style="color: rgb(255, 0, 0)">?</span>] luster.&quot;&nbsp; <span style="color: rgb(255, 0, 0)">Actually, this coin has virtually ALL of its luster</span>. Looks at the grainy appearance between the UNITED down to the eagle&#039;s head. Should be frosty, but there&#039;s no luster left. Sharp detail but no originality. Someone wiped it fairly harshly.&quot;&nbsp; <span style="color: rgb(255, 0, 0)">Now, we are back to this:&nbsp; I can <b>HARSHLY POLISH </b>the entire original surface of a Mint State coin until the round piece of metal (our coin) has the details of an About Good <span style="color: rgb(179, 0, 0)">AND IT WILL STILL HAVE COMPLETE LUSTER (the reflection of light from its surface); yet that luster will appear different from the original mint luster it had before it was polished. <span style="color: rgb(0, 89, 179)">That&#039;s why buffed, cleaned, and whizzed coins are so attractive to the less informed collectors who buy them.&nbsp; They have luster! </span>&nbsp; </span></span>[/QUOTE]</p><p><br /></p>
