1 Stiver - George III Trial Strike

Demerara and Essequibo — the twin Dutch colonies on the Guiana coast — had been seized by Britain in 1803 and existed in a peculiar administrative limbo for years afterward, still using Dutch stivers and guilders alongside whatever coinage could be sourced. The 1813 issue was a deliberate attempt to impose British colonial currency on a population that had no particular reason to trust it. Trial strikes in gold-plated copper were produced to evaluate the design before committing to a full production run.

The colonies were formally united as British Guiana in 1831, rendering this transitional coinage short-lived by design.
