Quote:Significant design and security features of the innovative PCGS holders include:
1. Proprietary polymer formula with embedded PCGS identifiers: Made from a new blend of crystal-clear, scratch-resistant plastic that's tested to be 99.99% chemically-inert. The chemical formula contains PCGS-specific additives that can be detected using a special handheld device. These sturdier, tamper-evident holders have no edge seam, are virtually airtight and will provide even more protection against potential environmental damage to coins.
2. Quick Response Code: A QR Code on each label conveniently links directly to the PCGS Certification Verification page at
http://www.PCGS.com/cert3. Embedded hologram with detectable additives: Additives in the embedded hologram and label will allow PCGS to determine the authenticity of the new holders.
4. New PCGS Secure™ Shield logo: The logo doubles as a security device, and contains micro-text and color shifting features.
All of which sounds wonderful if you're examining the slab in hand and you can use your handheld special polymer detector, your hologram additive detector and your microscope to read the microprinting. I don't really see how any of that really helps when all you've got to judge is a picture on
, or in an auction catalogue. And by the time you've got the fake slab in hand and realise its failed the tests, the counterfeiters or their local accomplices have already spent your money and disappeared.
