Question on card returned as "Miscut"

On my most recent submission I had a 1958 Allstar card returned which PSA would not holder and the sleeve PSA sends back had a notation of "Miscut". I thought that a miscut was a qualifier and that the card would receive a grade with a "MC" qualifier. There was also a notation of "N-8". I called customer service for clarification. I was told that PSA would not grade "hand-cut" cards (which I undestood) but I explained that this was not a hand cut card - this was a 1958 Topps Allstar card. They checked futher and said the N-8 meant it was an abnormal factory cut. Still don't understand why it wasn't graded with a "MC" designation. Can anyone shed any light on this? As always all of your comments are appreciated.

i dont really remember what they looked like to be honest.. i knew they'd grade low because of corner wear, but i wont know what caused the MC until i get it back i guess..
