10 Pesos El Banco Nacional de Mexico

El Banco Nacional de México was established in 1884 through the merger of the Banco Nacional Mexicano and the Banco Mercantil Mexicano, giving it a federally privileged position no provincial bank could match — including the exclusive right to operate in Mexico City and a preferred status in government transactions. That political backing made its notes the closest thing Porfirian Mexico had to a national currency before the Revolution scrambled everything.

The American Bank Note Company held the printing contract for most of this long series run, and the plates were used across multiple date ranges with relatively minor modifications. Notes from the later years of the window — post-1910 — occasionally turn up with revolutionary-era overstamps or counterstamps applied by regional authorities during the upheaval.
