Vintage 1 Cruzeiro banknote from the República dos Estados Unidos do Brasil

This appears to be a physical specimen of a historical Brazilian banknote, denominated as 'UM CRUZEIRO'. The note bears text identifying it from the 'REPUBLICA DOS ESTADOS UNIDOS DO BRASIL' and features a central portrait consistent with the image of Joaquim Marques Lisboa, the Marquis of Tamandaré, as indicated by the inscription 'MARQUES DE TAMANDARE' circling the vignette. This design is stylistically consistent with notes issued mid-20th century, specifically the first Cruzeiro series printed by the 'AMERICAN BANK NOTE COMPANY', whose name is visible in the lower margin. The note displays red serial numbers '000588' and series numbers '2452', along with printed signatures for the officials 'MINISTRO DA FAZENDA' and 'DIRETOR CAIXA DE AMORTIZAÇÃO'. Visible condition issues include significant signs of circulation such as heavy creasing, multiple folds (both vertical and horizontal), edge wear, and notable foxing or discoloration throughout the paper substrate. The intricate engravure and guilloché patterns are typical of high-quality security printing of that era, though authenticity as a legal or historical artifact remains unverified without professional physical inspection.

Based on my examination of the provided image, I am looking at a 1 Cruzeiro banknote attributed to the Republic of the United States of Brazil, featuring a portrait consistent with the Marquis of Tamandaré. The design and 'American Bank Note Company' imprint suggest a series produced from the 1940s through the 1950s. While the engraving details appear consistent with period security printing, I cannot verify the substrate's integrity or the presence of specific security features such as watermarks or paper texture from a photograph alone. The banknote shows heavy signs of circulation, including significant vertical and horizontal creasing, edge fraying, and widespread discoloration/foxing. In the numismatic market, condition is paramount; the 'Very Good' to 'Fine' grade suggested by these images significantly limits the value compared to uncirculated specimens. This specific denomination was printed in massive quantities, making it common in the current collectors' market. The estimated value reflects what similar mid-20th-century Brazilian notes in circulated condition typically command among hobbyists. To confirm the status of this item, a physical inspection by a numismatist would be required to verify the paper quality and ink depth. If this were found to be a contemporary reproduction or a fantasy piece rather than an official issue of the period, the value would be negligible. Because these items were produced by the millions, the market demand remains relatively low for circulated examples, and the valuation assumes the note is a legitimate historical artifact of the era.
