I would guess the cards were cut not sanded. I wouldn’t want to try sanding a card.

I don’t have anything against a .5 grade scale in general, but think little of PSA’s version which seems to be a crude concoction of the marketing and accounting departments. For examples, there is no 9.5 (presumably to protect the market sanctity of 10s), and if you resubmit a holdered card they can raise the grade .5 but they promise not to lower it. A collector can argue whether or not those are good things, but they ain't about objective accuracy in grading. The latter example sounds a bit like Harvard grade inflation.

I understand and appreciate wanting a numeral and name system that matches collectors' sensibilities (5-77 skip by 3 scale wouldn't be a swell idea for anyone). However, beyond these pleasantries, grading should be about one thing: grading. If it's about something else, you've got it wrong.
