1/8 Sovereign - Elizabeth II The last shilling

The "last shilling" framing references Britain's decimalization of February 1971, when the shilling ceased to be legal tender as an independent denomination — though it briefly survived as the five new pence piece. Tristan da Cunha, a British Overseas Territory so remote it has no airstrip and receives supply ships only a handful of times annually, issues commemorative coinage through the treasury arrangement but has no independent monetary circulation of its own.
