25 Pfennig - Rothenburg ob der Tauber Röder Tor

Rothenburg's Röder Tor notgeld was issued during the inflationary chaos of 1921, when German municipal and commercial bodies flooded the market with emergency coinage to compensate for the chronic shortage of small-denomination Reichsmünzen. Rothenburg was unusually prolific in this regard, producing numerous iron and zinc pieces across multiple denominations — partly out of necessity, partly because the town had already identified tourism as an economic engine and notgeld carried promotional value as collectibles.

Iron was the material of last resort, prone to corrosion in circulation. Uncorroded survivors in any condition are the ones worth examining closely.
