It’s ultimately your decision, but I have seen similar cards receive 7s, 8s, and even a few 9s. Given PSA/Ludkins current grading discounts, if you have 25 cards that you are planning on submitting I’d say it’s worth a shot.
As I previously mentioned grading is subjective, so you never know given the grader at PSA, but I’d say if there truly aren’t any other flaws on the card, it’s worth submitting. Even if it does get a 6 or whatever grade you aren’t satisfied with, you can always crack it out and keep it as a binder card.
