25 Pesos – Argentina

The shared design features Argentina's central coat of arms with "REPVBLICA ARGENTINA," "$ 25," and "2015." It is surrounded by the shields of all participating countries.

It features a geometric, symmetrical design centered on the Wiphala and the Argentine National Pavilion, symbolizing equality and respect for Indigenous peoples. Surrounding arches bear the inscriptions "X SERIES IBEROAMERICANA" above and "RAÍCES CULTURALES - WIPHALA - EMBLEMA DE LOS PUEBLOS ORIGINARIOS" below. The Wiphala is a 7x7 grid of 49 squares, its colors—yellow, orange, red, violet, blue, green, and white—alluding to the rainbow, with each color represented in seven textured squares.
