The main currency of Costa Rica is Costa Rican colón.

The Costa Rican Colon (ISO code: CRC) is the currency of Costa Rica. The currency is subdivided into 100 centimos. Many places in Costa Rica accept the US Dollar unofficially. The name of the Colon is derived from the Spanish explorer Christopher Columbus (Cristobal Colon in Spanish).

The Colon has historically been tied to the USD based on a "crawling peg" so that exchange rates changed monthly. However, in 2006 that tie was severed as the Colon was becoming "undervalued". Now the Colon managed within a band of exchange rates relative to the USD.
