<p>[QUOTE=&quot;lkeigwin, post: 1531399, member: 30400&quot;]March of 2010. Secure Plus takes a digital scan of both sides of each coin and stores it. Any coin resubmitted through SP is easily identified. And doctoring can be ID&#039;d.</p><p><br /></p><p>Soon after the &quot;Big One&quot; was announced PCGS introduced The Sniffer. It is used on all SP submissions to detect foreign substances used to improve the appearance of a coin. Putty, nose grease, and treatments like Blue Ribbon and Coin Care are detected.</p><p><br /></p><p>Along with the above PCGS began plus grading.</p><p><br /></p><p>Many question the value of SP, especially given the backdoor of an ordinary submission that bypasses digital fingerprinting, sniffing, etc. Some like the idea that stolen coins can be identified. But really...with the holes in the process...it isn&#039;t that effective, IMO.</p><p>Lance.[/QUOTE]</p><p><br /></p>
