Updated: Mar 21, 2022

This Brazilian banknote represent the 3rd denomination of the Cruzado Novo (Series 1989). The Cruzado Novo was a short-lived currency, which circulated from 15 January 1989 and 15 March 1990. It replaced the previous Cruzado, at a rate of 1,000 Cruzados to 1 Cruzado Novo. As the earlier Cruzado underwent rapid inflation, during its short 1986-1989 circulation.

Notably the last 3 denominations of the Cruzado served, as overprinted provisional Cruzado Novo notes. Such as this particular denomination, based on the 10,000 Cruzado (1988). The overprinted stamp revalues the note to 10 Cruzado Novo. Although it should noted due to raising inflation (of the Cruzado Novo) a non-stamped variant was never issued.

In 1990, the Cruzado Novo was replaced at par (1:1) by the Third Cruzeiro.


The observe features a portrait of bacteriologist Carlos Chagas (1879-1934), discover of Chagas disease. He discovered the disease in 1909, while working at the Oswaldo Cruz Foundation.
