Frank WakefieldBrian has it correctly assessed.
It will get a 1.
And when it does, you'll be dissatisfied with the results.
At present you have a nice card that you like. I like it. Once it gets slabbed, you'll have a slabbed card you're unhappy with, and you paid for that!
Admittedly, I have an EXTREME bias against the slabbing of cards. I broke an E90-1 out last night, to put in a book with my others. So I wouldn't get this card of yours slabbed. But even the slabheads (which are the majority on this board) see that you shouldn't slab this card. Unless you've got a megabuck buyer lined up for this card, with the price agreed upon and very high, on condition that the card will grade.
I'd leave it alone. And I'll also wager you send it off to get graded.
