20 Pounds Ulster Bank

Ulster Bank's interwar £20 notes are uncommon survivors. High-denomination commercial bank notes from this period circulated almost exclusively within business-to-business transactions — retail use was essentially nil — and the relatively small number issued meant few passed through enough hands to show serious wear. That same low-volume issuance, however, also means the surviving population is genuinely thin.

Charles Skipper & East handled security printing for several Irish commercial banks during this period. The "Northern Ireland" attribution in the printer credit reflects post-partition reorganization of Ulster Bank's operational base after 1921.
