<p>[QUOTE=&quot;Insider, post: 2506810, member: 24314&quot;]Folks, this cleaned/not cleaned thing is not complicated. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie104" alt=":yawn:" unselectable="on" unselectable="on" /> </p><p><br /></p><p>Detecting improperly cleaned coins can be/is being taught in grading seminars.&nbsp; You cannot be color blind.&nbsp; Then all that is needed is good eyesight, and proper examination technique (tip &amp; rotate coin at the same time through the light).&nbsp; JP Martin, describes this as making the coin &quot;light dynamic.&quot;&nbsp; Most improperly cleaned coins can be detected WITHOUT magnification. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie57" alt=":jawdrop:" unselectable="on" unselectable="on" /> </p><p>&nbsp;</p><p>The only things that cause difficulty is that many collectors/dealers couldn&#039;t tell a cleaned coin if you scrubbed it with a Brillo pad right in front of them!&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /></p><p><br /></p><p>Knowledgeable collectors/dealers have their own subjective standards for what is acceptable and what is not so even professional graders can disagree in certain cases.&nbsp; Next, we have crooks who know a coin is cleaned yet choose to ignore it.&nbsp;&nbsp; Then there are the ignorant dealers/collectors who see a few random bright hairlines on a coin and think that it is harshly cleaned. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie57" alt=":jawdrop:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie52" alt=":hilarious:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie52" alt=":hilarious:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie52" alt=":hilarious:" unselectable="on" unselectable="on" /> Finally, there are degrees of cleaning with <span style="color: #b300b3">both proper and improper </span>treatment.</p><p><br /></p><p>If I clean a coin and you cannot tell (no evidence left from the conservation) - IT IS NOT CLEANED! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie7" alt=":p" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie85" alt=":smuggrin:" unselectable="on" unselectable="on" /> Simple as that. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie11" alt=":rolleyes:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
