8 Doubles - Elizabeth II

Guernsey retained its own bronze coinage long after most British dependencies had surrendered monetary independence to Westminster, and the Eight Doubles denomination is the most direct continuation of a series stretching back to 1830. The "double" — one-eighth of a penny — existed nowhere else in the British Isles, a unit of account peculiar to Guernsey's Norman-rooted fiscal customs.

By the end of this issue's run in 1966, decimalisation planning was already underway in London, and the entire doubles series was abolished outright in 1971 along with the old sterling system.
