5 Pounds - Elizabeth II Photo, 1953

Tristan da Cunha holds the distinction of being the most remote permanently inhabited island on Earth, roughly 2,800 kilometres from the nearest landmass. The island has no airstrip; supply ships call perhaps six times a year. Its coins are legal tender in name but have never circulated — the handful of permanent residents use Saint Helena pounds for daily transactions, and issues like this one are produced entirely for the philatelic and numismatic export market through contracted mints.

The 1953 photograph referenced in the title was taken during the Coronation year, making this a commemorative of a commemorative moment.
