1 Pound - Elizabeth II (Centenary of the House of Windsor, George V)

The House of Windsor name was adopted by royal proclamation on July 17, 1917, when George V abandoned the dynastic name Saxe-Coburg and Gotha under intense public pressure during the First World War. Anti-German sentiment had reached a point where even the royal family's dachshunds were reportedly kicked in the streets. Tristan da Cunha, as one of the most remote permanently inhabited islands on Earth, issues commemorative coinage largely as a revenue mechanism through the philatelic and numismatic trade rather than domestic circulation — the island's population has never exceeded 300.
