The 100 Pesos bimetallic series, launched in 2006, commemorated each of Mexico's 31 states plus the Federal District through individually designed silver centers — one of the most ambitious regional commemorative programs any central bank has undertaken in a single run. The Durango piece honors a state whose silver mining history around Santa Bárbara and the Sierra Madre Occidental made it one of colonial New Spain's principal sources of the very metal sitting at the coin's core.
