100 Pesos

Banco de México opened in 1925 as the country's first true central bank, replacing a fragmented system in which dozens of private banks had issued their own competing notes. This 100 Pesos belongs to the institution's earliest emission series — the notes it needed in circulation quickly to establish credibility and displace the old commercial paper still passing through the economy.

The American Bank Note Company contract was a practical choice: ABNC had printed Mexican currency through the Porfiriato and Revolution years, and the new central bank inherited both the relationship and much of the existing intaglio infrastructure. The long date range across a decade reflects reorders rather than a single uninterrupted print run.
