Ulster Bank £50 note
The Ulster Bank £50 note is a banknote issued by Ulster Bank. It is valued at fifty pounds sterling and the current design was first issued in 1997. 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. Design

Released in 2022, the polymer (plastic) £50 banknote celebrates Northern Irish industry with such features as a Pine marten, gorse flowers, a loom worker, and scientist. The paper £50 note was olive and green in colour. The obverse side featured the Ulster landscape, with Belfast Harbour, the Giant's Causeway, flax plants and Celtic knot patterns. The reverse showed the Ulster Bank coat of arms, and the arms of the provinces of Ireland. References
