Interesting
So I can still get Luffy's bounty right ---> 3,500,000,000
Then I guess Kidd's is either 3,150,000,000 (callback to the bounty he was introduced with) or 3,470,000,000 (meanining a 3,000,000,000 bump from his current bounty)
As for Law I'd say a round 3,000,000,000 or a bit more, like 3,200,000,000 (even here, a callback to his original 200,000,000)
