50 Pence - Elizabeth II Dolphins, head with tiara

Gibraltar's heptagonal 50 pence series from this period served a dual administrative purpose: issuing a distinct local coinage that nonetheless remained legal tender at parity with the pound sterling. The dolphin subject was no accident — the Strait of Gibraltar hosts one of the densest common dolphin populations in the western Mediterranean, and the territory had been using marine wildlife imagery on its coinage since the 1980s to reinforce a distinct Gibraltarian identity separate from both Britain and Spain.

KM#778 ran across six years without design modification, suggesting steady local demand and no production controversies worth recording.
