The Ulster Bank £100 note is a banknote issued by Ulster Bank. It is valued at one hundred pounds sterling and the current design was first issued in 1990. As with most banknotes of Northern Ireland, they can be used for transactions in the Isle of Man and Great Britain, but in practice most retailers will not accept them and they are not legal tender in England, Scotland or Wales.
