The H&S catalog today came and low and behold they've got an S81 Matty slabbed by SGC for sale!

In 2012 at Baltimore I begged and begged the previous administration to slab one for me, and they assured me there was no way it would fit, and that they couldn't slab them.

When/how did they start slabbing these? I'd appreciate any info you have concerning S81s and SGC.

Here's an image from the H&S catalog.
