1 Mil Réis Thesouro Nacional, 6th print

The Thesouro Nacional's reliance on the American Bank Note Company throughout this period reflects Brazil's near-total dependence on foreign printers for secure currency production — the country lacked domestic facilities capable of the intaglio work required. The 6th print designation distinguishes this from earlier impressions of the same basic design, issued across a span of years that saw significant monetary instability tied to coffee export cycles and mounting government debt.

ABNC's New York plant handled multiple Brazilian series simultaneously during the 1870s and 1880s, which occasionally creates attribution confusion between issues. This is one of the lower-denomination Mil Réis notes and circulated heavily — surviving examples in better condition are disproportionately scarce relative to higher denominations from the same print runs.
