| Obverse description | The Mexican national coat of arms occupies the central field, depicting a Mexican golden eagle with spread wings perched on a prickly pear cactus atop a rock, devouring a serpent in its beak and talons. The eagle is rendered in fine relief with detailed feather work, and the base of the cactus is flanked by a laurel branch on the left and an oak branch on the right, tied with a ribbon. The circular legend ESTADOS UNIDOS MEXICANOS arcs above in Latin characters, and a beaded border runs along the inner rim. |

| Additional information |
In 1916, Mexico was deep in the chaos of its revolution, with Carranza's Constitutionalist government struggling to establish monetary credibility against competing factions. This copper pattern — struck as a test piece for a proposed gold 20 Pesos issue bearing the Aztec Calendar — never entered circulation. The gold version itself was only minted in tiny quantities, and these copper trials represent an earlier phase of deliberation over whether the design and specifications were viable for actual coinage production.
Surviving examples are exceptionally rare; fewer than a handful are documented in major collections.
