In 2005 to celebrate Legendary Fighting Ships, the Royal Mint on behalf of the Solomon Islands released a very Limited Issue Trireme Galley $25 Twenty Five Dollar Silver Proof Coin struck in solid .999 Silver weighing one ounce of pure Silver.
The reverse depicts the Trireme Galley while the obverse features a portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
