Issued in 1970 by Banco de México, this note commemorates Mexico's indigenous heritage through the central Aztec Sun Stone, one of the most important pre-Columbian artifacts. The reverse features the Independence Monument, reflecting Mexico's celebration of its post-colonial sovereignty during the 20th century. The inclusion of 'MÉXICO, D.F.' above the date represents the administrative marking of Mexico City as the capital and issuing location.

The obverse centers on the Piedra del Sol (Aztec Sun Stone), an elaborate circular pre-Columbian calendar stone featuring intricate geometric and symbolic representations. This sacred artifact is surrounded by ornate baroque-style decorative borders with floral medallions positioned in all four corners and shield emblems in the corner cartouches. The reverse prominently displays the Monument to Independence (Monumento a la Independencia), a tall commemorative structure topped with a victory figure, symmetrically framed by matching decorative elements and baroque borders. Both sides employ red serial numbers and incorporate institutional designations for banking officials (Consejero, Interventor, Cajero). The overall aesthetic combines pre-Hispanic indigenous iconography with European baroque design principles, reflecting Mexico's cultural synthesis.
