| Obverse description | The Mexican national coat of arms dominates the central field, depicting a Mexican golden eagle perched upon a prickly pear cactus growing from a rocky outcrop, devouring a serpent clutched in its beak and talons. The design is rendered in fine detail with the eagle's wings partially spread. Oak and laurel branches frame the base of the design in a wreath. The circular legend ESTADOS UNIDOS MEXICANOS arcs along the upper periphery, bordered by a continuous ring of beads. |

| Additional information |
Pattern coinage from the Casa de Moneda rarely surfaces in public sales, and the 1980 brass 20 centavos sits in that murky category of pieces produced for internal evaluation rather than any announced program. Mexico's monetary authorities were actively reconsidering the circulating alloy mix throughout the late 1970s as inflation eroded the purchasing power of small denominations — the 20 centavos was already a dying unit by this point. The Pick-Lissner pattern reference anchors it institutionally, but the surviving population is effectively unknown.
