1 Guilder - George III

The United Colony of Demerary & Essequibo was a Dutch-origin territory under British administration from 1803, and its coinage situation was a persistent headache for colonial authorities. Dutch stivers, Spanish reales, and assorted foreign silver circulated simultaneously, with no coherent local standard. The 1816 issue — produced in London — was part of a broader British colonial effort to impose monetary order on the Guiana territories before they were formally consolidated into British Guiana in 1831.

Struck in relatively small quantities, these guilder pieces bridged Dutch monetary tradition with British imperial administration, retaining guilder denomination while bearing George III's authority. The .816 fineness matches the old Dutch standard rather than British sterling.
