1961- 62 Post , how do you grade them?

Is it based on margins, how much of the black lines show??
Got a bunch in, but clueless on how to grade them.

In order for PSA to actually assign a grade to any of the cards that possess visible/defined borders on all four sides, evidence of that border must be present. If the cut exceeds the visible border for the card in question, PSA will encapsulate the card as "Authentic" only. If the card is severely undersized and suffers in overall eye-appeal, the graders may deem the card not suitable for authentication or reject the card as minimum sized altogether.
Keep in mind that, for cards that do not possess visible/defined borders, the cards must still fall within a certain size requirement for that particular issue in order to qualify for an actual grade. In other words, the borders must be virtually full in order for a grade to be rendered. Otherwise, as stated above, a label of "Authentic" will be assigned or, in some cases, the cards may fall short of the size requirement altogether. This is not an exact science, however, PSA will do its best to provide consistent guidelines for these types of cards.
PSA suggests that, in order to achieve the highest grades, the cuts of the cards should be relatively close to the visible borders without exceeding the limit. Cards that exhibit a clean, accurate and properly shaped cut have the best chance at achieving the highest grades. Eye-appeal is very important. When it comes to excess paper or cardboard around the edges of the visible borders, the graders will place significant importance on overall eye-appeal. Keep in mind that all cards of this type will be designated as "Hand-Cut" on the PSA label for accuracy.

"...looking at the scan suggests to me you have a bunch of VG/Authentic cards...."
