25 Mil Réis 3rd.Banco do Brazil, Series A,B,C

The Banco do Brazil of 1856 was not the modern state institution but a private bank chartered in 1853 — Brazil's third entity to carry that name. This 25 Mil Réis note, issued across three series, was produced by the American Bank Note Company at a moment when ABNCo was still consolidating its dominance over South American currency contracts, having absorbed several competing New York security printers in the preceding years.

The three-series structure (A, B, C) suggests successive authorizations rather than a single print run, likely reflecting the bank's expanding note circulation through the late 1850s before mounting pressures on convertibility began to undermine public confidence in private Brazilian paper.
