<p>[QUOTE=&quot;GDJMSP, post: 1253178, member: 112&quot;]Again, no. The &quot;sniffer&quot; does not detect that a laser has been used on a coin, nor does it detect that a coin has been whizzed. The &quot;sniffer&quot; only does 1 thing - it detects the presence of a foreign substance on the coins.</p><p><br /></p><p>What you are doing is mixing up two entirely different things - Secure Plus and the Sniffer. Secure Plus is what allows PCGS to detect that a laser was used on a coin. (It&#039;s not even needed for whizzing for that can be detected by eye.) However, and it seems most people don&#039;t understand this, Secure Plus can only detect the use of a laser <u>after the fact</u>. In other words, the only way that Secure Plus works is if a coin is submitted under the Secure Plus grading tier - twice.</p><p><br /></p><p>Example - a coin is submitted to PCGS for grading. It is <u>not</u> submitted under Secure Plus. The coin is graded MS64 and returned to the submitter. Later, that person sells his coin. The buyer (who happens to be a coin doctor) then cracks the coin out, uses his laser to remove several hairlines and then he submits the coin to PCGS again. This time the coin is graded MS65, or even MS66, by PCGS. The coin doctor gets his coin back from PCGS and sells it for a whole lot more money.</p><p><br /></p><p>Now you&#039;re going to ask why did PCGS do this ? Why didn&#039;t they detect that the coin was lasered ? Easy answer, because they can&#039;t. It cannot seen - unless it is subjected to high magnification. And that is not done when doing standard grading.</p><p><br /></p><p>That&#039;s where Secure Plus comes in. Had the original buyer above submitted his coin under the Secure Plus grading tier, that costs extra, the coin would been photographed with a very high resolution digital camera that captures even the tiniest detail and the tiniest flaw. This means those hairlines on the coin that held the grade down are captured forever. That photograph is then stored in the PCGS database. </p><p><br /></p><p>Now, the same scenario comes about. The original buyer sells his coin, a coin doctor buys it. He cracks the coin out, uses his trusty laser and basically erases the hairlines. Then he submits the coin to PCGS, again under Secure Plus. </p><p><br /></p><p>This time, when PCGS gets the coin, they again that take a high resolution picture of the coin and that new picture is run through the database. This time the coin, without the hairlines, is identified as having been doctored. The coin is rejected for grading and returned.</p><p><br /></p><p>However, if that coin doctor submits his doctored coin under one of the regular grading tiers, (and he&#039;d have to be an idiot not do so because they know how to read too) the coin is not photographed again, its picture is not run through the database, and again the doctoring escapes detection and the coin is upgraded and retuned in a new PCGS slab. Once gain to be sold to the unsuspecting public.[/QUOTE]</p><p><br /></p>
