500 Pesos El Banco de Londres y Mexico

The Banco de Londres y México was the oldest commercial bank in Mexico, established in 1864 as a branch of the London Bank of Mexico and South America. It held a privileged position under the Díaz concession system, one of only two banks authorized to issue notes with national circulation — the other being Banamex. That duopoly made high-denomination issues like this one instruments of serious commercial and industrial finance, not everyday exchange.

The American Bank Note Company printed for the bank across several decades, with plate designs updated at intervals that complicate precise dating within the 1889–1913 window. The series was rendered void following the 1913–1914 banking collapse triggered by the Revolution.
