Wunsiedel is a small Franconian town near the Czech border, and like hundreds of German municipalities in 1918, its Stadtmagistrat issued emergency small-change notes — Kleingeldscheine — to compensate for the near-total disappearance of low-denomination coins from circulation. Copper and nickel had been systematically requisitioned for war production since 1916, leaving ordinary commercial transactions without a workable medium below the Mark level.

The DeNG reference places this within a documented series for Wunsiedel, suggesting the municipality issued multiple denominations under the same authorization. Paper quality on these municipal issues varies considerably — many were printed on whatever stock was locally available by the time the armistice approached.
