5 Pounds Bank of Ireland

The Bank of Ireland was still operating under British authority when this note was issued — the Irish Free State would not come into existence until December 1922, and the Currency Act establishing a separate Irish pound followed only in 1927. Notes from this exact window carry an odd dual status: legally British-era instruments that survived into the new state's early circulation, since the Free State initially allowed existing bank notes to continue as legal tender during the transition.

Pick 87 is among the harder dates to pin precisely within the 1920–1921 run, as dating relies on manuscript date entries rather than printed series identifiers.
