100 Dollars

Guyana's 1977 gold issues were produced to mark the country's transition to a cooperative republic, a political framework instituted under Forbes Burnham that repositioned the state as the dominant force in the economy — including nationalization of the bauxite and sugar industries. The .500 fineness is notably low for a commemorative gold coin of this period, a deliberate cost-containment measure that allowed the government to issue prestige coinage without committing significant gold reserves.
