1 Pound Provincial Bank of Ireland

The Provincial Bank of Ireland was a London-chartered institution — founded by act of Parliament in 1825 — that operated a network of provincial branches specifically designed to reach areas underserved by the Bank of Ireland. That structural rivalry shaped the bank's entire commercial identity. Notes circulated through rural Ulster, Munster, and Connacht in volumes that Belfast or Dublin banks rarely matched at the branch level.

The 1903–1918 date range straddles a turbulent stretch: the Home Rule crisis, the outbreak of the Great War, and the Easter Rising of 1916. Notes from the later end of this span would have circulated under genuine political uncertainty about what Irish banking regulation might look like within a decade.

Pick 337 is notoriously difficult to date precisely from physical examination alone, as branch cashier signatures vary considerably across the run.
