Welcome, Joe!
I don't see why it wouldn't grade numerically. The borders don't look any smaller than an AB back typically would; in fact, they actually look bigger than most AB borders. So I would think either PSA or SGC would be fine for submitting.
As for value, PSA typically may net you a higher resale value if/when you sell, and SGC may be cheaper to submit and certainly will turn the card around and get it back to you quicker.
Good luck!
