5 Pounds - Elizabeth II Queen Elizabeth's and Prince Philip's Birthdays

Tristan da Cunha is among the most isolated permanently inhabited islands on earth — roughly 2,400 kilometers from the nearest landmass — and issues coins primarily as a revenue source rather than for general circulation. This piece commemorates both the 90th birthday of Elizabeth II and the 95th of Prince Philip, a coincidence of milestone ages that gave the issuer justification for a joint theme. The island's actual currency in daily use is the pound sterling; locally issued coinage rarely if ever changes hands on the island itself.
