Burg an der Wupper was absorbed into the newly consolidated city of Solingen in 1929, which makes its independent municipal notgeld issues a brief footnote to a place that ceased to exist as an administrative unit within a decade of printing them. The 1921 date puts this squarely in the second wave of German municipal emergency currency — after the inflation pressures of 1919–1920 but well before the hyperinflationary collapse of 1922–1923 that rendered such denominations meaningless.

The DeNG reference suffix 9/16 indicates a specific date variant within the 209.1 type, suggesting the city issued this denomination across multiple dates — common practice for Bergisches Land municipalities trying to maintain circulating small change as coins vanished from commerce.
