As some people have said before, Zoro and Sanji's bounty come from their birthday:
Zoro November 11th : 1.101.100.000
Sanji March 2nd : 1.032.000.000
In comparison, Mihawk's and Crocodile's is based on a pun on their names.
Mihawk --> Mi(3) Ho(Go=5) Ku(9) --> 3590
Buggy --> Ba(Ha=8)Gi(Gu=9) --> 3189
Crocodile --> Ku(9)Ro(6)Ko(Go=5) --> 1965
Jinbe's bounty is partially a gag to troll Sanji
1. Usually very close to Zoro is Sanji, but this time it's Jinbe.
2. To make Sanji's bounty once again the 4th highest. Back then 3rd were Robin, then Usopp, and now Jinbe. Why 4th? Because of 4th nakama, 4th in popularity poll, 4th child, etc.
So, what do you think of Bounty being like this? In one hand, it's thematic and unique to those characters. On the other hand, Luffy's and Zoro's feels greatly downplayed.
