1/2 Guilder - William IV

Demerara and Essequibo had functioned under a patchwork of Dutch colonial monetary conventions long after British forces took permanent possession following the Napoleonic Wars. The guilder-denominated coinage issued under William IV was a deliberate accommodation to that legacy — local commerce still operated in Dutch units, and the Crown chose to meet it rather than force an immediate transition to sterling. This series was struck at the Royal Mint, London, and had a short production window that closed when the colony was formally merged into British Guiana in 1831, with coinage running into the transition years as existing authority was wound down.
