Can I use coinage from the Channel Islands or the Isle of Man?

The Channel Islands and the Isle of Man are Crown Dependencies of the United Kingdom. They have their own legislative and taxation systems and issue their own banknotes and coins. These, in common with United Kingdom coins, bear the portrait of Her Majesty The Queen. However, they are only legal tender within the Crown Dependencies themselves. If you are in possession of coins of the Channel Islands or the Isle of Man, please contact the issuing authority of the relevant Crown Dependency.
