No they don't. I have a Tinker pin from this set that I wanted graded and asked at the last philly show. Seems they had no plans to do so either. I wish they could expand a few times, and adjusted the current holder to different sized should not be too hard.
I assume PSA was able to use resources from the coin division to get the the pin slabs done.
I also am hoping SGC gets an autograph guy in soon. I really can't stand the large Beckett holder for auto cards plus I already have some in SGC holders.
