If this is really true, then it needs to be made public to protect the remaining collectors... otherwise, we are going to get some very serious problems. If it's no longer possible to distinguish between originals and fakes, the entire field is 100% dead. It will die a slow D E A T H. Even coins with a clean history will no longer find a buyer.
Since when exactly have these faked CAS holograms been in circulation ??
The first time I held fake CAS holograms in my hand was in 2022/3. But the way Mikes' holograms were made used some very clever security techniques. Extremely advanced for 2011 and still easily hold up today. The only way to truly copy the hologram would be to have the "master". The physical engravings have encoded info above 10k DPI (probably E BEAM tech so 100k DPI) and can't truly be copied to the level where an auction house would struggle to know the difference.
Document security is typically split into four levels, with forensic being shared with the auction house. The fourth level is only known to the manufacturer.
I can say with confidence that we've been researching these security risks for obvious reasons. I'm not overly concerned for the future of collectibles.
