R.W. Dinnendahl was a Ruhr-area machinery and engineering firm operating during the industrial expansion of the Kaiserreich period. Like dozens of Ruhr industrial concerns, it issued small-denomination zinc tokens to circulate as wages or canteen currency among its workforce — a practice that sidestepped chronic small-change shortages in German industrial towns without requiring Reichsbank authorization. The Menzel reference numbers confirm this as a documented notgeld-adjacent company issue rather than a speculative or fantasy piece.
