Well, never say never. I had recently bought this 2010 MMA collection to break up and sent some cards to SGC (first ever “modern” submission). For thick cards it seems they have this holder that can’t be custom-sized like their standard black gasket.
Most cards made it into holders but 3 from the same subset were deemed too large to encapsulate. And these aren’t overly thick so it had to be height or width exceeding the holder size.
