70 ECUs - Elizabeth II HMS Victory

The ECU — European Currency Unit — was a basket currency used as an accounting unit within the European Monetary System from 1979, never physically issued by the European Community itself. Gibraltar exploited this gap throughout the 1990s, producing gold and silver ECU-denominated pieces that were legal tender locally but existed primarily as bullion collectibles timed to European monetary unification. The denomination became obsolete almost immediately: the ECU was replaced by the euro on 1 January 1999.

HMS Victory, launched at Chatham in 1765, had already seen forty years of service before Trafalgar.
