1 Cent Pattern

By 1940, the fall of France to Germany had left the Indochinese colonial administration politically isolated and materially cut off from metropolitan supply chains. The zinc pattern coinage of this period reflects the Vichy-aligned administration's scramble to establish local production capacity under Japanese pressure — Japan having effectively assumed military control of the territory that same year. Whether this pattern was ever seriously considered for full production is unclear; the occupation's accelerating disruption of normal commerce made large-scale zinc coinage increasingly academic.

Zinc itself was a wartime compromise material, prone to corrosion in tropical humidity — a practical liability that likely contributed to the pattern never advancing further.
