1 Penny - Elizabeth II 4th portrait, St. Helena Dependency

Tristan da Cunha is the most remote permanently inhabited island on Earth, roughly 2,400 kilometers from the nearest landmass. Its coins are issued as legal tender but function almost entirely as collector items — the island's population of around 250 has historically used South African rand and British pounds for daily transactions. This 2008 penny was struck under the "St. Helena Dependency" designation, reflecting the administrative arrangement that placed Tristan under St. Helena's governance until the two territories were separated under the 2009 British Overseas Territories restructuring.
