100 Cruzeiros Thesouro Nacional, 2nd print, Autographed

Brazil's Tesouro Nacional issued this series — not the Banco do Brasil or the later Banco Central, which only came into existence in 1965 — a distinction that still trips up collectors sorting mid-century Brazilian paper. The 2nd print designation separates it from earlier Thomas De La Rue production runs of the same design, though the visual differences between printings are subtle and the autographed classification refers to the manuscript signatures of treasury officials applied to individual notes rather than facsimile printing.

De La Rue had maintained a near-continuous relationship with Brazilian note production since the imperial period, making London the de facto press for Brazilian government currency through much of the twentieth century.
