100 Pesos Nayarit

Part of the long-running Mexican states series issued by the Casa de Moneda beginning in 2003, this Nayarit piece was one of twenty-six bimetallic commemoratives planned to cycle through each of Mexico's federal entities over roughly a decade. The .925 silver core is unusually fine for a circulation-intended bimetallic — most comparable programs use lower alloys to suppress melt value.

Nayarit, carved out as a state only in 1917 from the Tepic Territory, had been administratively marginal for most of the colonial and post-independence period.
