“The bounty is 50 crowns a head, 50 sovereigns for their leader, a spellcasting priestess of a fish. Deal is that if you help us kill the beasties, you can have first pick of the loot, but we keep the heads. Sahuagin craft might not sound the most appealing, but their equipment works wonders in the water, making them quite valuable to sailors like the quartermaster or whoever you think would want to buy.”

In layman’s terms, a single Sahuagin was worth 50 silver, which was 5 gold coins, though their leader is worth 50 gold alone. You won’t get to benefit directly from this bounty as Azure specifically wants the heads to turn in herself, however you’ll be allowed to keep anything else the Sahuagin have as plunder, which may be considerably more valuable depending if you can find a buyer. The Master-Of-Arms, Thoral, was at least interested in their spears, so that’s someone who would buy your plunder.
