10 Pesos Tlaxcala - Silver Proof Issue

Part of Mexico's long-running "Estados de la República Mexicana" series, which committed the Casa de Moneda to producing a proof silver issue for each of the country's 31 states plus the Federal District. Tlaxcala — the smallest state by area — is historically notable as the Tlaxcalan confederation's alliance with Hernán Cortés proved decisive in the fall of Tenochtitlán in 1521, a political calculation that haunts Mexican national identity to this day.

KM#682 is the Tlaxcala assignment within that sequence, struck to the .999 fineness the series adopted from the outset rather than the .925 used in earlier Mexican commemorative programs.
