SGM is only for modern cards. The larger issue, I think, is that all "professional card grading" is proving to be merely a 2nd opinion and often not a very good 2nd opinion, at that. As a business, it stinks (see the CLCT - aka, PSA - stock price as a good indictator), but more importantly, they don't know what they're doing, based on the arbitrary/biased/incorrect results they produce.
Plastic tombs aren't only annoying, they're also bad for collecting.
