5 Pounds Bank of Ireland

The Bank of Ireland's post-war £5 series ran through several signature combinations, and the Guthrie/Chestnutt pairing places this note squarely in the mid-to-late 1960s window — a period when the Republic was still printing its own notes independently before the later consolidation of Irish note-issuing arrangements became a more contentious political topic. Both signatories appear as "Agent" rather than Governor or Chief Cashier, reflecting the Bank of Ireland's internal structure, where branch agents held signing authority on circulating notes.

Pick 57 is not a rare type, but issued examples with clear, legible agent signatures are worth examining carefully — ink strike quality on this series varied noticeably by printing run.
