Total speculation, I think an educated buyer would pay up to 20% more for a LEAF with a new battery pack. Unfortunately, finding an educated buyer will take time...
Otherwise, you might get an extra 10% from someone who is buying an EV for the first time and doesn't really understand the importance of the health of the battery pack.
I'd be surprised if you can get more than $8,500 for it.
