I don't know what the company policy is, but periodically SGC is going to receive a card that is uncatalogued and which they have never seen before. So it will entail more than just grading, as they will have some decisions to make. The first is what to put on the label. In this case it is logical to call it an E93 black and white, but it is within the realm of possibility that it is something else. So I think in a situation like this it is safer to just authenticate it, assuming they believe it is period and not some later production.

Calling it E-Unc. would make more sense but perhaps the submitters wouldn't like that and would lobby for something a little more specific. This is all speculation of course.
