Collect treasure from defeating ships and monsters if you have a ship with cannons. You can buy a ship in Dragon Cove (north-western island).* Once you have cannons, a way to get lots of doubloons is by sinking sea creatures (around Dragon Cove) and pirates (between the Pirate Outpost and Golden Harbor). When they sink, they release a large amount of salvage. Sea creatures are generally easier to escape because they are slower and do not shoot back. But this takes practice, and groups of sea creatures or pirates may attack at the same time, and sometimes a mix of these.
