History & Notable Facts
The 1915 1 Peso from Sonora was struck using silver recycled from melted-down Spanish reales, a practical necessity during the Mexican Revolution's supply shortages.
That makeshift approach gave the coin its distinctive, often irregular appearance. Weighing about 16.66 grams and measuring 34 millimeters across, it featured a simple design: the Sonoran state seal on one side and the denomination on the other. Minted in Hermosillo under revolutionary authorities, it circulated briefly in a region gripped by conflict.
Exact mintage figures are unknown; records from that era were spotty at best. What we do know is that these coins helped finance the Constitutionalist cause against Huerta's forces. Not every piece survived the years, making survivors a quiet curiosity for those who dig deeper.
For a coin born of rebellion, it's amusing how it now sits peacefully in collections, far from any gunfire.
