SG, LLC = SGC or = scam?

I have yet to have an old SG or SBC slab not get reholdered unless the centering was way off. The centering tolerances were much looser back then.

Thanks.
Very helpful.

Just heard back from SGC. Yes, they’ll convert the old 100 point grades by SG, LLC and SGC to the new 10 point grades upon reholdering. Thanks again for the earlier responses.
