In 2007 to celebrate famous bridges from the United Kingdom, the Royal Mint released a special Limited Issue £1 One Pound Silver Proof 4 Coin Set all struck in solid .925 Sterling Silver.
Each coin carries the Ian Rank Broadley's portrait of the Queen on the obverse, whilst each reverse features a bridge representative of one of the four constituent parts of the United Kingdom. On each reverse, it has the customary beading of the £1 One Pound Coin. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
