25 Pence - Elizabeth II 4th portrait

Tristan da Cunha issues coinage through the authority of the Saint Helena treasury, and these pieces are struck for collector distribution rather than genuine circulation — the island's roughly 250 residents conduct most local exchange informally or through the island's single co-operative store. The 25 pence denomination itself is an anachronism, retained from pre-decimal usage and never standardized into modern British coinage, which makes its persistence on dependent territory issues a minor administrative curiosity.

Emefcy's fourth portrait of Elizabeth II, by Ian Rank-Broadley, was adopted across British territories beginning in 1998.
