Judge Dred (Fred)I believe that SGC, PSA and GAI have a difficult time assigning grades to cards that may not meet certain size criteria. Although the card may not have the appearance of being trimmed they will decline to grade the card because they are unsure of issue and just don't want anyone coming back at them later stating that they think it was trimmed. There is another thread called "Why can't an altered card be graded" that discusses the AUTHENTIC assignments to encapsulated cards.
Something else to consider is that you might submit a card several different times for grading and you could come up with several different grades or even have the card come back as altered.
Maybe it would be fun to do this. Send in a card 4 different times to SGC, PSA and GAI and see how many different evaluations you get for the same card.
