Banknote credit: Townshend & Son; photographed by the National Numismatic Collection
Siege of Mafeking currency was issued by the British commander, Colonel Robert Baden-Powell, during the 217-day siege for the town of Mafeking (now Mahikeng) in South Africa from 13 October 1899 to 17 May 1900, during the Second Boer War. To ease the problems caused by the lack of genuine banknotes, Baden-Powell authorised the issue of siege banknotes in late 1899. Made by Mafeking printers Townshend & Son using woodcut printing, notes were backed by the Standard Bank of South Africa and issued in denominations of one-, two-, three- and ten-shilling coupons, as well as one-pound notes, of which 620 were printed. The intention was that, after the siege was over, these could be exchanged for genuine currency, but in practice few were; most were kept as souvenirs.
This picture shows a ten-shilling note from the Siege of Mafeking, dated March 1900; it is now in the National Numismatic Collection of the Smithsonian Institution's National Museum of American History.
