10 Pounds - Elizabeth II Battle of the Somme

The Battle of the Somme, which opened on 1 July 1916, produced the single bloodiest day in British military history — approximately 57,470 British casualties before nightfall. Guernsey, under British Crown dependency status, had contributed men to the conflict through mainland British recruitment; the island's population was small enough that losses registered with particular weight in individual communities.

The centenary commemoration year of 2016 saw dozens of issuing authorities produce Somme-related pieces. Guernsey's five-ounce format places this squarely in the bullion-adjacent commemorative category rather than anything intended for circulation.
