160 Réis - Pedro I

The 160 réis denomination was a direct product of Brazil's monetary reorganization following independence in 1822, when the newly sovereign empire needed coinage that was distinctly Brazilian rather than Portuguese colonial restrikes. Pedro I's government retained the colonial base of réis accounting but introduced new fractional values — 160 réis among them — calibrated to the silver content available from domestic and imported bullion stocks.

The three-year window of this issue reflects how quickly the denomination fell out of practical use once the monetary system was revised again in the late 1820s.
