Thad may have to verify, but if memory serves I think the question stems from a video made by PCGS regarding the sniffer. In that video they show a picture of some of the things that the sniffer will detect. And I&#039;m thinking the picture shows a bottle of Verdi-Gone, the predecessor of Verdi-Care. And I think Thad once said that the sniffer could not detect Verdi-Gone in a thread where that video was discussed because Verdi-Gone would completely evaporate and leave no trace on the coin. But because Verdi-Care leaves behind a protective film I would think that the sniffer could detect it.</p><p><br /></p><p>But like I said, I&#039;m going completely by memory here, so Thad will have to verify.</p><p><br /></p><p>I said:</p><p><br /></p><p>As Jimski&#039;s quote of Verdi-care description, the layer on the coin surface is&nbsp; permanent, and as such is not volatile and could not be detect by any sniffer analytic device. The outermost layer is water soluble, so if any thing, one&nbsp; might observe any reflection,as thus&nbsp; it can can removed with water and water can be removed with acetone, so a 2 step rise and you have the coin surface pure again ( get it slabbed fast as it may turn before PCGS gets it done)&nbsp; or leave protected if you are not submitting it ( no rinse). Now if TPGs start using mass or x-ray spectro, it might detect the graders DNA&nbsp;&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />&nbsp;&nbsp; There is such a thing as too much sensitivity.&nbsp;&nbsp; Jim</p><p><br /></p><p>P.S.&nbsp; Acetone removes black permanent marker quite well from coins.[/QUOTE]</p><p><br /></p>
