1 Dollar

The Bank of Guyana was established in 1965, just months before independence, and this note belongs to the first sovereign currency series — replacing the Eastern Caribbean dollar that had circulated under British administration. The 26-year date span reflects design continuity rather than a single print run; Thomas De La Rue produced multiple printings across that window, with signature combinations and date prefixes distinguishing them.

Pick 21 is one of the longer-lived low denomination issues in the Caribbean region, which itself points to how slowly inflation eroded the one-dollar unit's purchasing utility in Guyana during this period — a country that would eventually require notes in the tens of thousands by the 1990s.
