Yep long gone now days. I had several friends that worked for them as graders and a couple that were attribution specialists, for awhile they even had some signed variety slabs, I always thought for the most part PCI got it right as to grading (at least in the classic coinage) not so sure in the modern aged stuff. Their attributions were usually really good also.
But nope - no way to look up the certification that I know, nor was there any way in the past even when they were around.
