50 Pula 50 Years of the Bank of Botswana

The Bank of Botswana was established in 1975, a decade after independence, making this commemorative issue a marker of half a century of central banking in one of Africa's most financially stable economies — a stability built almost entirely on diamond revenue managed through the Pula Fund, the country's sovereign wealth vehicle. Oberthur Fiduciaire, now operating as part of the IN Groupe network, has printed Botswana's currency for much of that history.

Paper substrate on a commemorative issue in 2025 is a deliberate choice — most anniversary notes at this tier have moved to polymer.
