50 Pence - Elizabeth II WWI - Battle of Cambrai

The Battle of Cambrai in November 1917 is widely credited as the first large-scale deployment of tanks as a coordinated offensive weapon, with the British fielding over 400 machines along a six-mile front. The initial breakthrough was dramatic enough that church bells were rung in England — a gesture reserved for victories, and one that proved premature when a German counterattack recovered most of the ground within days.

Jersey's WWI centenary 50 pence series ran across multiple battles and fronts. The gold-plated steel format kept the issues accessible while mimicking a more precious appearance — a distinction worth noting for any collector cataloguing the series by metal type.
