In my opinion, the game’s economy has some issues right now.
The Chest of Legend used to be extremely valuable — people would steal it, and naval battles were fought over it. But with the introduction of new loot, it has started to lose its importance. (The same applies to other older treasures.)
For example:
Chest of legend - 8.600~11.000
Wrathful King's Bounty Skull - 5.100
The golden rum/exquisite paintings - 10.000
Chest Of Fortune - 20.000
Orb of Secrets - 20.000
Skull of siren song - 50.000
Smugglers Heist Target Painting - 175.000
Now I can just kill two skeleton captains or loot a sunken ship and earn the same amount of money.
