| 正面描述 | The silver centre features the Mexican national coat of arms: an eagle displayed in left profile, perched on a prickly pear cactus growing from a rock amid water, grasping a serpent in its beak and talons. The design is rendered in fine relief against a plain field. The encircling aluminium bronze ring bears the national legend ESTADOS UNIDOS MEXICANOS along the upper arc, with a laurel and oak branch tied with a ribbon at the base. |

Part of Mexico's long-running "Estados de la República Mexicana" series, this issue commemorates the state of Coahuila — one of 32 coins released between 2003 and 2009, each pairing a .925 silver center with an aluminium bronze ring. The Casa de Moneda de México produced these in both proof and circulation strikes, though the bimetallic construction made consistent ring-to-core bonding a minor but documented production concern across the series.
Coahuila shares its northern border with Texas, a boundary fixed only after the Texas Annexation of 1845 and the subsequent Treaty of Guadalupe Hidalgo in 1848.
