1 Pound Jersey Bank - Amiraux, Le Breton & Co

Jersey Bank — formally trading as Amiraux, Le Breton & Co — was one of several private banking partnerships that emerged in the Channel Islands during the Napoleonic period, when disrupted trade and military expenditure created urgent local demand for paper credit instruments. These were not chartered institutions but merchant partnerships assuming banking functions, which made their notes legally precarious and entirely dependent on the personal credit of the signatories.

Both Matthew Amiraux and William Le Breton signed individually, as was customary for partnership notes of this type — each signature a personal guarantee rather than an institutional one. The firm did not survive long into the nineteenth century, and surviving notes from this issue are genuinely rare.
