20 Joes / 440 Guilders

Demerara and Essequibo had been under British administration since 1803, but Dutch colonial financial conventions died hard. This note's dual denomination — 20 Joes alongside its guilder equivalent — reflects a monetary system still tangled between Dutch accounting units and the practical reality of British rule, decades after the handover. The Joe, a corruption of "Johannes," derived from the Portuguese gold coin long used as a reference unit in the Guiana trade.

The colony was formally absorbed into British Guiana in 1831, meaning notes dated within this series straddle the exact moment the issuing authority itself ceased to exist.
