50 Colones

The Banco Internacional de Costa Rica was the country's sole official issuing authority from 1914 until 1936, created by the state specifically to displace private bank issuance. This 50 Colones sits near the top of the denomination range for the period — large-value notes in Central American circulation during the 1920s tended to live short lives and suffer hard use, making surviving examples rarer than the lower denominations from the same series.

ABNC held the printing contract for Costa Rican government notes across several decades, with New York engraving and plate work of consistently high quality. The serial number and overprint work on P#177 issues was completed before shipment south.
