South West African mark
The South West African mark was a temporary currency issued in South West Africa between 1916, after the withdrawal of the German South West African mark, and prior to the introduction of the South African pound in 1918.
A number of notes were denominated in South West African marks and pfennigs, especially by the Swakopmund Bookshop that issued 10-, 25-, and 50-pfennig, and 1-, 2-, and 3-mark notes.
