1 Colón Silver Certificate

Costa Rica's silver certificate issues of this period were backed by metal reserves held in the Banco de Costa Rica, a government institution that had absorbed the country's collapsed private banks following the 1900 monetary crisis. The silver-certificate mechanism was an attempt to restore public confidence after years of inconvertible paper, essentially offering holders a legal claim on specie rather than a bank's word.

The American Bank Note Company held the printing contract for most Central American government paper of this era, and the Costa Rican series used their standard intaglio security printing. ABNC's work is generally consistent across this run, though the series spans four years and minor plate variations exist between early and late impressions.
