Brazil's Thesouro Nacional turned to Perkins, Bacon & Petch at a moment when the firm's intaglio security printing was considered among the most counterfeit-resistant available — a real concern in a country that had already suffered damaging note forgeries earlier in the century. This is the second print of the series, meaning the plates had already seen prior use, though Perkins maintained exceptionally durable steel-engraved dies and plate quality rarely degraded perceptibly between print runs.
Jacob Perkins himself had pioneered the siderographic transfer process that made mass production of identical, fine-lined banknote engravings commercially viable. By 1844 he had been dead two years.
