5 Pesos

Chile's 1976 coinage reform followed the Pinochet government's broader economic restructuring under the "Chicago Boys," a group of economists trained at the University of Chicago who dismantled the previous socialist monetary framework and introduced a new currency series to signal fiscal stability. The 5 Pesos entered circulation as part of that overhaul, replacing denominations eroded by the inflation that had plagued the Allende years.

KM#209 is a short-lived type, discontinued after 1980 when ongoing inflation again made the denomination impractical.
