Marienburg's Stadtgeld issues were products of the post-WWI Notgeld wave that flooded Germany between 1918 and 1923, when municipal authorities printed emergency fractional currency to compensate for the chronic shortage of small-denomination Reichsmünzen. The Stadt Marienburg series is catalogued under the Grabowski reference system, and the 870.3 designation places this among the later, more deliberately produced collector-targeted issues — by 1921 many municipalities knew full well that philatelists and notgeld collectors were driving demand as much as genuine commerce.

The watermarked paper distinguishes this from the cheaper Notgeld produced on plain stock, suggesting a more deliberate print run rather than a hasty wartime stopgap.
