The Guanabarean Cruzeiro (sign: Cr$; code: GBC; also referred to as the cruzeiro; Cross in english, pl. cruzeiros) is the official currency of the Kingdom of Guanabara and its territories. It is divided into 100 smaller cent units, called centavos. The circulating paper money consists of banknotes produced by the Banco Central (Central Bank), located in Guanabara City.
The Cruzeiros has been used since the independence, although the design on the bills have changed since the first notes. Also during the dictatorship, all banknotes were taken out of circulation and replaced with others without any reference to the monarchy.
