In 2009, to celebrate Classic British Motor Cars, the Royal Mint on behalf of Alderney released a Limited Issue Bentley 4.5 Litre £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse design depicts a Bentley 4.5 Litre while the obverse has Ian Rank Broadley's portrait of Her Majesty Queen Elizabeth II.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
