James Stanley, the 10th Earl of Derby, held the lordship of Man under a feudal arrangement dating to 1405, when Henry IV granted the island to Sir John Stanley. By 1733, the Stanleys had long exercised near-regal authority over the island, including the right to strike their own coinage — a privilege that effectively ended when the British Crown purchased the island's feudal rights from the 12th Earl in 1765 under the Revestment Act, absorbing Man into direct Crown administration and terminating the Stanley coinage series entirely.
