General grading questions should be in The Giant Professional Grading Thread. I’ve locked this thread, and you’re free to re-post it there.
But as mentioned by @sparky55603 , with a general picture like that we can’t say anything about their potential grades. They could all be PSA 9-10 quality, but they could also all be 7-8 quality. If they’re pack fresh, most will probably be 8-9, depending on the amount of whitening on the backss and holo scratches present. But again, without close-up pictures of both the front and back we can’t give any indication about potential grades, and even with pictures the estimate will be mediocre at best, since most scratches and minor indents can’t be seen on pictures.
