That fake was from mid 2007 and I'd be very surprised if it was produced after NGC finally published that information in early 2008. I know there has has been a second improved generation of PCGS fake slab. The first generation of PCGS fake can be found imitating two different generations of PCGS slabs, one of which does not exist as a genuine slab, and also some fake "Genuine" slabs. I only know of one generation of fake ANACS slab. One problem is that I have not been able to get my hands on the latest generations of the fake slabs so I can't tell exactly how they differ from the earlier fakes.
