The Blue Chested Hummingbird Redux: 100 Cruzeiros Reais (Brazil, 1993)-Article

Updated: Mar 21

This Brazilian banknote represents the 2nd denomination of the Cruzeiro Real Overprint (Series 1993). This series was introduced as a stop-gap measure, before the introduction of the Cruzeiro Real. As the short-lived 3rd Cruzeiro was in the process of being replaced, due to high inflation. Which rose dramatically during its three years of circulation.

The Cruzeiro Real was even shorter-lived, it circulated from 1 August 1993 and 30 June 1994. The exchange rate was 1,000 Cruzeiros to 1 Cruzeiro Real. Notably the last 3 denominations of 3rd Cruzeiro were used as provisional notes. Such as this note, which was based on the 100,000 Cruzeiro (1992).

The overprinted stamp converts the note to a 100 Cruzeiro Real.


The observe features a detailed illustration of a Brazilian Ruby hummingbird, with its young. This species of humming bird is native to eastern Brazil. They can be seen along the edges of forests, parks, and gardens. They get their name from the reflective red feathers, around the male's throat. Although in some angles this red throat can appear black.

The note's header is off-set to the upper-left. It reads, the (trans.) "Central Bank of Brazil". Notably the second "O" (DO) roughly aligns with a faint security thread. Below the header is one of the note's dual-serial numbers (A 7050052830 A). The second number can be seen at the lower-right.

At the lower-left is a large number "100 000". Its (trans.) "Hundred Thousand Cruzeiro" text value is listed to the left. A second number "1 000" can be seen at the upper-right. Some distance below is a pair of signatures, representing the Minister of Finance (top) and Central Bank President (bottom).

Above these signatures is a butterfly registration element. Backlighting the note with bright light, will complete the light puzzle effect. Doing so will also expose a mirrored image of "República", opposite of the butterfly. To the right of the watermark, is an overprinted stamp. This stamp converts the note to a 100 Cruzeiro Real. Below the stamp is the motto "DEUS SEJA LOUVADO" (God Be Praised).


The reverse depicts Iguazu Falls, on the Argentinian-Brazilian border. Iguazu Falls is not a single waterfall, but a complex of waterfalls. It's largest of its type in the world and receives its name from the Guarani-Tupi words "y" and "ûasú" (big water). The falls are roughly 64-82 m (210-269 ft) tall and 2,700 m (8,858 ft) wide. Its closest counterpart is Victoria Falls, on the Zambia-Zimbabwe border.

Similar to the observe, the reverse has number "100 000"s at its upper-right and lower-left corners. Although the text value now extends from the lower center, to the far right. The before mentioned security thread roughly aligns, with the letter "I" in "Mil" (Thousand).

The underprint features a different design from the observe. Beneath the lower text is an alternating pattern of butterflies. At the center far-left is a single "butterfly, forming half of the observe registration element. The remaining underprint feature three shades of flowers. Transitioning from lilac (left), light green (center), and gray-brown (right).

Iridescent fibers can be seen on the note's unprinted sections.
