10 000 Bolivianos

Bolivia's wartime economy ran hot on tin — the country was the Allies' single largest supplier of the metal throughout the conflict, and the resulting export revenues drove sustained inflationary pressure that pushed denominations upward through the early 1940s. The 10,000 Bolivianos note was a direct consequence: a denomination that would have been unthinkable in the previous decade.

Thomas De La Rue's London plant produced the series despite wartime constraints on materials and shipping logistics across the Atlantic. De La Rue had held the Bolivian contract across multiple series by this point, and the engraving quality is consistent with their established standard for South American central bank work of the period.

Pick 146 was superseded within a few years by the 1945–1952 inflation spiral that ultimately forced Bolivia into a full monetary reform in 1963.
