After 15 October 2017, the Jersey £1 coin will no longer be legal tender. The States of Jersey will be withdrawing the coin from circulation to coincide with the UK’s timeline for the introduction of its new £1 coin.
The Royal Mint: the new pound coin
This decision will not affect the Jersey £1 note, which will continue to be legal tender, as will the new UK £1 coin when it comes into co-circulation on 28 March 2017.
The States of Jersey has no plans to issue a new £1 coin but will instead rely on the local £1 note and the new issue of UK £1 coins.
Any Islanders in possession of Jersey £1 coins or the existing UK £1 coins will have until 15 October 2017 to bank them or exchange them.
