500 Pesos

The Banco Internacional de Guatemala was one of several private commercial banks operating under Guatemala's pluralist banking system before the state moved to consolidate monetary authority. That system collapsed in 1926 when President Lázaro Chacón's government forced the liquidation of the private issuing banks and transferred their functions to the newly chartered Banco Central de Guatemala — which almost certainly explains the terminal date on this series.

A 500 Pesos denomination from a Guatemalan private bank is not a note that saw much counter use. At that face value, circulation would have been confined almost entirely to large commercial settlements and interbank transfers. Survivors in any condition are genuinely uncommon.
