<p>[QUOTE=&quot;Insider, post: 2350980, member: 24314&quot;]Thanks Doug...</p><p><br /></p><p>I&#039;ll comment on your post shortly.&nbsp; But I have one for you first.</p><p><br /></p><p>This past weekend at a grading seminar, one of the teaching coins was a&nbsp; typical Fine barber dime.&nbsp; The coin had the normal gray color found on naturally circulated worn coins and some darker surfaces highlighting the relief.&nbsp; The &quot;teaching coin&quot; had been dipped half way (just as your example).&nbsp; The coin was ugly - just as your example.&nbsp; The top half was natural and the bottom was dull etched bright gray.&nbsp; Comment from the teacher; &quot;This is why it&#039;s often best not to dip circulated coins. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Now to your post: </p><p><br /></p><p><br /></p><p><br /></p><p>Dipping it in what exactly ? And yeah, I&#039;m asking for the name of the commercial dip you use to do this.&nbsp; <span style="color: rgb(179, 0, 0)">The &quot;acid&quot; dip I use is e*Z*est coin cleaner (Aervoe Industries).&nbsp; I formerly used Jewel Luster.&nbsp; Don&#039;t know if this is made any more.</span></p><p><br /></p><p>The folks who have been around here a while have seen this picture many times. <span style="color: rgb(179, 0, 0)">Nice photo and good for teaching.&nbsp; I&#039;ll need to make one. </span>And it&#039;s obviously not a silver coin<span style="color: rgb(179, 0, 0)"> - obviously<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie104" alt=":yawn:" unselectable="on" unselectable="on" />,</span> and no the coin didn&#039;t even have any luster <span style="color: rgb(179, 0, 0)">(?)</span> as it was well circulated <span style="color: rgb(179, 0, 0)">(?) Sorry to disagree with you on this:</span></p><p><span style="color: rgb(179, 0, 0)">IMO, the top half of the cent is a beautiful AU-55+ to AU-58 lustrous brown&nbsp; Lincoln cent.&nbsp; You should have been ridiculed in the class if you graded the top half of that coin any lower than AU (and IMO you deserved the ridicule as we aren&#039;t in the 1960&#039;s anymore <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />)&nbsp; There is hardly any wear on the coin. </span>long before I ever got it. And this little experiment didn&#039;t even have anything to do trying to remove toning, it was about something else entirely, namely the lines <span style="color: rgb(179, 0, 0)">(?) </span>on the coin. <span style="color: rgb(179, 0, 0)">What lines? <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie5" alt=":confused:" unselectable="on" unselectable="on" /> <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie46" alt=":facepalm:" unselectable="on" unselectable="on" />Where is this going?<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie11" alt=":rolleyes:" unselectable="on" unselectable="on" /></span></p><p><br /></p><p>But, this does serve to illustrate a point. <span style="color: rgb(179, 0, 0)">?
