Slab veriation question for PCGS

mrpaseo

OK, it is to my understanding that there are currently 8 different slab veriations for PCGS.

How many other examples are there.

i.e. Authentication/example/novelty types

Please list all the types that you know of.

Thank you,
Ray

I have no idea. I rely totally on Condor101's knowledge. I hope he publishes a paper one day...
