500 Mil Réis Banco de Crédito Popular do Brazil

The Banco de Crédito Popular do Brazil was one of dozens of private banks that obtained authorization to issue currency during Brazil's Encilhamento — the speculative boom triggered by the Ouro Preto reforms of 1889–1890, which briefly allowed commercial banks to issue their own banknotes backed by government bonds. The experiment collapsed spectacularly within a few years, and most of these issuing institutions failed or had their privileges revoked before their notes saw meaningful circulation.

The American Bank Note Company printed for a large number of these short-lived Brazilian issuers simultaneously, producing handsome notes for institutions that in some cases never achieved genuine solvency. Whether this series ever circulated at scale is unclear — the bank's own history is poorly documented.
