Sanji has been the hero in the shadow of the SH. He saved the crew numerous times with his amazing tactics combined with strength (Little Garden, Mr. Prince, attacking the sea train alone, opening the Gate of Justice,...). However, the marines is highly likely in the dark about most of his tactical moments, so his current bounty (177m) probably only represents his strength, without his intelligence. As the title says, how much would Sanji's bounty be if the marines knew all what he did? Personally, I believe it should be higher by a large margin, raging from 200m - 300m. 2018 UPDATE: After Dressrosa, every Curly Hat members got a 50 million bounty rise, but Sanji himself got a 100 million rise, which means he got a 50 million inflation from his father. However, I believe what he did without the World Government knowing (especially his tactics as said above, not to mention his overlooked win over Bon-chan, whose bounty was 32 million then, in Alabasta) is more than enough to compensate for the inflation, so a bounty of about 350 million would better represent his current danger to the WG.
