Symeon III died before his dream was realized and his lazy son never followed up on the plans of his father. Only after "the incident" in the Mines of Hokar did Symeon IV fear for his life and start a search for the invaluable Toli Captains. The 33 coins are all "master work" quality items worth much more than their weight in gold, possibly 200-400 g.p. apiece to a collector (the Marquis has offered anywhere from 500-1000 g.p. for each). One side bears the likeness of a typical Port Toli captain while the other side is imprinted with a Sea Princes vessel. Due to their being lost in the cavernous Mines of Hokar, they are not pristine and most should be scratched and dirtied.
Notes for the DM: The golden Toli Captains are rumored to be magical or perhaps hold a resonating effect if they all gathered together. The ruler of Hokar's obsession over them and the fact they were minted by a mage is hard to dispute. Besides their ridiculously treasured value, the 33 coins are unfortunately just plain gold. The true motives of the Marquis (his father's dream) is to use the combined masterwork coins as a special tribute to the enigmatic pirate group known as the Fivefold Council in a bid to gain their unrivalled personal protection; the fabled Ward. Though there is no guarantee the Council will be pleased with this gift, the chance to impress them with a thematic work of art such as the Toli Captains is worth the time, money and effort (and deaths of PCs) for the slovenly Symeon IV who lacks the adventuring spirit of his forebears.
