I think the Northern Irish notes have a worse and more obscure place in England than the Scottish ones, up until last year there were 4 different issuing banks in Northern Ireland: Bank of Ireland, Danske Bank, Ulster Bank and First Trust Bank [who now no longer issue].

It's quite entertaining to handover a Danish-Irish-UK pound sterling note in the UK, like somehow the viking era never ended.

Not to mention the infamous Northern bank, which Danske Bank replaced. I don't think I've ever seen a note replacement scheme happen as quickly as the one that replaced all of the green Northern bank notes for purple ones after the Northern bank robbery, which I believe is still the largest amount of money stolen from a bank at once in UK history, right?

Indeed it was. Albeit it was a moot robbery as you say, given that every note taken was known to the bank, and the whole class was obsoleted within weeks
