Close-up of a newly minted silver coin featuring a high-relief engraving of an ancient Roman bireme warship with a square sail.

A newly minted and polished silver coin, featuring a high-relief engraving of an Ancient Roman bireme warship in side profile. The warship should clearly show two banks of oars, one above the other, extending from the hull. The ship has a prominent ram at the bow, a high sternpost, and a single mast with a square sail. Details like rigging, a small deckhouse, and perhaps a stylized figurehead or decorative elements on the bow and stern should be subtly visible in the high relief. See more
