10 Pounds

The Currency Commission Ireland was actually in its final administrative days when this note was printed — the Commission was dissolved and replaced by the Central Bank of Ireland in 1943, meaning the 1941–42 print run of this denomination effectively closed out the Commission's entire note-issuing history. Brennan served as Commission Chairman; McElligott was Secretary of the Department of Finance, an unusual pairing that reflects how closely the Irish state kept monetary operations tied to the civil service rather than an independent banking structure.

High-denomination Commission notes survived circulation poorly — the £10 was a substantial sum in wartime Ireland, and examples that did circulate were heavily used. Waterlow printed on a distinctive rag paper with an embedded watermark, the only security feature employed on the series.
