The Columbian Bank Note Company of Chicago printed relatively few banknote contracts for non-American clients, making this series an outlier in the printer's portfolio. The National Bank of South Africa Ltd. was a commercial institution, not a central bank, and its notes circulated alongside those of several competing private banks during a period when South Africa had no unified currency authority — that consolidation only came with the South African Reserve Bank Act of 1920.

The date range spans the Anglo-Boer War's aftermath and the long transition toward Union-era monetary reform. Notes from the earlier years of this span are considerably scarcer than those from the 1910s.
