1 Penny - James Murray

James Murray, 2nd Duke of Atholl, held the feudal lordship of Mann under a purchase arrangement with the British Crown that dated to 1736. The 1758 copper coinage was struck under his authority — one of the last exercises of private manorial coinage rights in the British Isles before Westminster moved to curtail them. Parliament's Revestment Act of 1765 transferred the island's revenue and customs rights back to the Crown for £70,000, ending the Murray family's ability to issue currency entirely.
