1 Pound Jersey Bank - Hamon

The Jersey Bank was a private commercial institution, and its notes from this period circulated in a jurisdiction that sat outside the formal English banking system — Jersey had no obligation to conform to Bank of England restrictions, which gave local issuers considerable latitude. Ph. Hamon's signature here places this note within a narrow window of the bank's operation, and the London printing is consistent with the practice of Channel Island issuers engaging metropolitan trade engravers for prestige and reliability rather than local production.

Notes from Jersey's private banking era before the 1830s are genuinely uncommon survivors. Most circulated hard in a small, cash-dependent island economy.
