This classic Mexican definitive stamp features the nation’s coat of arms — an eagle perched on a cactus devouring a serpent — a powerful Aztec symbol representing triumph and resilience. Issued in the early 20th century, likely around the 1910s–1920s, it bears the inscription “CORREOS MEXICO” and the denomination “CINCO CENTAVOS.” Printed in an ornate orange-brown tone, this issue belongs to Mexico’s long-running “Eagle” series used widely during the Porfirio Díaz and revolutionary eras. Its intricate frame and typography reflect early Mexican engraving styles, and the stamp often appears with various postmarks from regional offices.
