Hi there. I've got a copy of Silk 1 that I had sent in to be graded, but it came back NG and said it's coverless. I had spoken with Customer Service and they said to resubmit it as a mechanical error and put a note stating it is a cover misprint, but it still came back as coverless. Could I get some information on why this isn't considered a cover misprint? It's got the same number of pages, same back cover, and the first and last pages are the same. The information I'm finding online is that the cover of this issue is the back cover of issue 1 B that was misprinted on this issue.
