In 2000 to celebrate the Millennium, the Royal Mint on behalf of the Kiribati and Samoa released a very Limited Issue $5 Five Dollar Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse has Prometheus with his gifts of fire (Technology) gazing at the planets of our solar system as they revolve in perfect alignment around the sun while the obverse has the Coat of Arms of Kiribati and Samoa.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
