1/2 Guilder - George III

Demerara and Essequibo were administered as a single British colonial unit following the formal cession from the Dutch in 1814, but the monetary system lagged well behind the political transfer. The Dutch guilder remained the unit of account, and this 1816 issue was struck specifically to bridge that gap — British authority, Dutch denomination, circulating among a population still conducting daily commerce in the old currency.

The Prid#16 reference places this among the British colonial pattern and proof documentation, and surviving examples in any grade are scarce. The territory merged with Berbice to form British Guiana in 1831, after which guilder-denominated coinage became obsolete almost immediately.
