The Deutsche Notenbank was the East German central bank from 1948 until its replacement by the Staatsbank der DDR in 1968. This 1964 issue came at a relatively stable point in the GDR's monetary history — post-Wall, post-currency chaos, before the late-sixties institutional reshuffling. The Staatsdruckerei der DDR handled all DDR banknote production in-house, a deliberate policy choice that kept the printing process entirely within state infrastructure.

A print run of just over twelve million is modest by Western standards but typical for a denomination that saw genuine circulation in a controlled economy with limited consumer purchasing options. Watermark-only security reflects the DDR's reliance on paper quality and controlled distribution rather than sophisticated anticounterfeiting technology.
