The Princess Louisa,  a huge East Indiamen ship, was lost on April 18th, 1743 on Galleons Reef, in the treacherous waters off the Cape Verde Islands, near the Isle of May. Her holds carried Spanish Colonial cob coinage, from the mints of Potosi, Bolivia and Lima, Peru.

Although crudely struck, The Obverse of these cobs features a pillars-and-waves design (symbolizing the Pillars of Hercules), the latin words "Plus Ultra" (more beyond), and the date denomination, mintmark and assayer. The Reverse of these cobs features a bold cross (symbolizing the union of Church and State), and the lions and castles that symbolize the merger of the medival kingdoms Leon & Castilla.
