Comments	Pick 38 covers a long run — over a decade — during which Mexico's economy was absorbing the aftershocks of Cárdenas-era nationalization and then riding a wartime export boom. The Banco de México kept the 1 Peso note in production throughout rather than replacing it with coinage, partly because wartime metal shortages had pulled silver out of everyday commerce. ABNCo's New York presses handled the full print run, a common arrangement for Mexican small-denomination paper of this period. Serial number prefix variations across the 1943–1954 span are the primary tool for dating individual examples within the series.
