4 Pence - Edward VII

The fourpence — known colloquially as the "groat" — survived in British Guiana long after it had become obsolete in Britain itself, largely because the coin aligned conveniently with the Spanish-derived currency systems already embedded in local commerce. The colonial authorities continued issuing it specifically for Guiana and the West Indies precisely because local merchants demanded a denomination that circulated nowhere else in the empire by that point.

Edward VII's reign produced only a handful of date varieties within this short window, and the series ended with his death in May 1910.
