Scientists, aboard the CSIRO research vessel (RV) Investigator, have explored the deep-sea and ocean abyss, discovering amazing and unique creatures of the deep. The Royal Australian Mint celebrates these journeys of scientific endeavour, and the wondrous creatures they discovered with this 2023 $10 ‘C’ Mintmark Gold Proof Coin.

The reverse of the coins shows the CSIRO research vessel (RV) Investigator and its deep tow camera, as well as brittle star (Ophiuroidea), gold coral (Chrysogorgia), and spiny king crab (Neolithodes flindersi).  With the presentation carton also depicting the beautiful gold coral in glorious colour.
