50 Pounds Ulster Bank

Ulster Bank's 1997 £50 is one of the higher denominations in the pre-polymer series issued before the bank's gradual design consolidation in the 2000s. De La Rue's London production for Ulster Bank was longstanding — the relationship predates this issue considerably, and the security specification here is relatively modest for a £50 note of that period, relying on a basic watermark and thread rather than the more sophisticated features De La Rue was simultaneously producing for other clients.

Ulster Bank notes, though legal currency in Northern Ireland, are not legal tender anywhere — including Northern Ireland itself — a distinction that continues to cause friction at points of exchange outside the province.
