1 Peso El Banco Nacional de México

The Banco Nacional de México was formed in 1884 through a merger of the Banco Nacional Mexicano and the Banco Mercantil Mexicano, and almost immediately received preferential concession rights from the Díaz government — including the privilege of issuing notes redeemable at face value for tax payments. That arrangement gave its paper a practical credibility that competing state bank notes lacked, and the 1 Peso circulated widely as a result across a genuinely long production window spanning nearly three decades.

ABNC held the contract throughout, printing from New York on intaglio plates. The series ran long enough that signature combinations across the issue are numerous, and some combinations are considerably scarcer than others.
