10 Centavos

This long-running type spans nearly five decades and three major political regimes, surviving Argentina's shift from the oligarchic República Conservadora through the Radical governments of Yrigoyen and Alvear and into the early Concordancia period. The coin outlasted two world wars without a composition change — unusual given Allied pressure on copper-nickel supplies during 1914–18. Production was handled by the Casa de Moneda de la República Argentina in Buenos Aires throughout the entire run.

The series encompasses dozens of catalogued die varieties across the CJ references, with date punch differences and mintmark-style shifts distinguishing early from late emissions. The 1942 issue closed the type just before wartime metal economics forced a broader rethink of Argentine coinage alloys.
