Mark TTry this: Take a hack saw or small saw and cut off a small area near the 8.5 corner. Then use a flat head screwdriver and start to pry the cut corner open. As you do this the card should be on a flat surface with a towel below it. once it starts to separate use your fingers to help take off the top.
Of course be as gentle as possible....
I took one card out of a PRO holder and if i remember it was a bit tough but it came out undamaged. Never did a CSA but i am sure it will crack out just as the other graders do.
