The P#59 series had an unusually long production run for a Mexican low denomination — thirteen years across multiple signature combinations, with the ABNCo contract reflecting Mexico's continued reliance on foreign security printers well into the postwar decades despite periodic nationalist pressure to develop domestic printing capacity. The Banco de México would not fully consolidate note production at its own facilities until the 1970s.

Signature varieties within this series are the primary driver of value differentiation among collectors. Early dated examples from 1957 are considerably scarcer than the high-volume printings of the mid-1960s.
