Historical Context
The 5 centavos coin of 1921 was issued during the Portuguese First Republic, a period marked by political instability and economic difficulties, especially in the aftermath of World War I. After the establishment of the Republic in 1910, Portugal adopted the escudo as its new monetary unit, divided into 100 centavos. Low-denomination coins, such as the 5 centavos, played an essential role in daily life, facilitating everyday transactions in an economy facing inflation and a shortage of higher-value metallic currency.
This issue is part of the bronze series produced between 1920 and 1922, representing an effort by the republican regime to standardize the monetary system.
