10 Mil Réis Banco do Brasil, 1st. Print

Banco do Brasil's relationship with the American Bank Note Company ran deep through the early twentieth century, and this 1923 10 Mil Réis belongs to a production run that coincided with Brazil's chronic post-WWI inflationary pressure — the milréis was losing ground steadily, and mid-denomination notes like this one moved through commerce quickly and wore out accordingly. Circulated survivors in presentable condition are genuinely harder to locate than the face value might suggest.

The "1st. Print" designation matters here: ABNC produced subsequent printings with subtle plate differences, and the first print is distinguished in specialist literature primarily by the signature combinations on the face rather than any obvious typographic change.
