I have seen SGC grade frameless backs with a number, with AUTH, and not grade at all. I have seen PSA grade frameless cards with a number and not grade at all (I don't recall seeing a PSA AUTH frameless).
Alot of this depends on the degree of the cut and when it was submitted.
On the subject of Obaks, each grading company has an even more uneven history of dealing with factory stamps on Obaks (all three years). Its possible to see an Obak w/ stamp in a PSA MK or without. Its possible to see an Obak w/stamp in SGC straight grade (no downgrade or mention of mark), SGC graded down due to mark, SGC labeled "factory stamp" with straight grade.
Argh.
