1 Centavo Pattern

Pattern coinage from Argentina in this period was driven largely by ongoing debates over metal allocation, with the government weighing copper against aluminum and other alternatives as the country sought to modernize its fractional currency. KM#Pn50 represents one of several trial strikes tested before the eventual redesign of Argentina's minor coinage in the early 1940s. Patterns of this type rarely escaped the mint in quantity.

Copper was ultimately abandoned for the centavo denomination in favor of cheaper alloys as wartime supply pressures tightened across South America through the early 1940s.
