100 Colones

The American Bank Note Company produced this series during a period when Costa Rica's central bank was still finding its footing — the Banco Central had only been established in 1950, replacing the older Banco Nacional as the country's sole currency-issuing authority. This note belongs to the first generation of issues under that new institutional arrangement.

ABNC's intaglio work on Costa Rican paper from this period is generally clean, but the 100 Colones denomination circulated heavily and worn examples dramatically outnumber uncirculated survivors.
