1 Peso Compañía Minera 'Las Dos Estrellas'

Las Dos Estrellas was one of the most productive gold and silver mines in Mexico, operating in the mountains of Michoacán under Anglo-Mexican management. During the Revolution, the federal banking system collapsed entirely, and mining companies, haciendas, and local merchants across the country began issuing their own scrip — not as a political act but out of sheer necessity, because there was simply no other medium of exchange reaching remote industrial camps.

These company notes, known collectively as *bilimbiques*, were redeemable only at the company store and payable to workers in lieu of coin. The mine continued operating well into the 1930s; nationalization came in 1959.
