<p>[QUOTE=&quot;GDJMSP, post: 3459781, member: 112&quot;]I think, stress think, there&#039;s some confusion on this part of your comment. I believe it was Thad&#039;s original product, Verdi-Gone, that he claimed could not be detected by the sniffer. That&#039;s because Verdi-Gone did not leave a coating on the coin. That said, PCGS claimed Verdi-Gone could be detected by the sniffer in a video they made and put out on the subject. Who&#039;s right ? I don&#039;t know, I guess it depends on which one you want to believe. But if Thad&#039;s right and it leaves nothing behind, then I&#039;d be inclined to believe him. But that&#039;s me.</p><p><br /></p><p>As for Verdi-Care, the sniffer can and will detect any foreign substance on a coin, including the coating left behind by Verdi-Care.</p><p><br /></p><p>Regarding the question of will a coin treated with Verdi-Care straight grade ? The answer is it depends - it might straight grade and it might not. </p><p><br /></p><p>Why, and on what does it depend ? Two things, 1, if the sniffer is used or not. <b>IF</b> the sniffer is used the coin will not straight grade. <b>BUT</b>, the only coins on which the sniffer is used are those coins submitted under the Secure Plus grading tier. The sniffer is not used on any other coins that are submitted under of the other grading tiers. So if you submit the coin under any of the other grading tiers - it has a chance of being straight graded - but just a chance.</p><p><br /></p><p>That brings us to 2 - because it still depends on whether or not one of the group of graders grading the coin happens to notice the coating with his eyes. If one notices it, the coin will not straight grade. If one does not notice it, it will straight grade. </p><p><br /></p><p>So how likely are they to notice ? That also depends on the individual graders, some are better than others at detecting things like that. There are other products that also leave a coating on the coins, for example Coin Care or Blue Ribbon to name a couple. And there have been many coins treated these products that did not straight grade because somebody noticed, and at the same time others that did straight grade because nobody noticed. </p><p><br /></p><p>What makes it so subjective ? A couple of things really, including the condition of the coin. Here&#039;s why. When you put a coating on a coin it changes the appearance of that coin, if quite often makes the coin look better than it really is, particularly the surfaces. If the coin is MS, that&#039;s not much of a big deal really. But if the coin is not MS, depending on how much wear it does have, graders get used to coins in various conditions having a certain look. So if the coin is a XX, and it looks better than a XX should look - then it makes the grader suspicious. And once a grader gets suspicious, you&#039;re pretty well shot down. And then there&#039;s the quantity factor. In other words, the more of the product, whichever one it is, that you use on the coin, the more of it there is that will be left behind. And if more is left behind it is easier to see.</p><p><br /></p><p>Bottom line it&#039;s a crap shoot.</p><p><br /></p><p>All of this also applies to NGC because they have the exact same policies in place.[/QUOTE]</p><p><br /></p>
