GrilloMy understanding is that all of the big 3 will slab a trimmed card at the request of the customer and label it "authentic" or in the case of SGC "AUT"...again, normally the customer will send in a trimmed card and notify the company in advance that the card is most likely trimmed; next they ask the company to slab the card if it is indeed trimmed. Even though a card is labeled authentic and encapsulated, that card cannot be part of their registry.
Again, this is my understanding...
