25 Pfennig - Werne a. d. Lippe

Werne an der Lippe issued this iron notgeld piece in 1920 as the postwar coinage shortage left German municipalities scrambling to produce their own small-denomination currency. Iron had been a wartime substitute material, and many cities continued using it into the early Weimar period simply because the infrastructure for striking it was already in place. Werne, a small Westphalian coal-mining town, had neither the resources nor the prestige of larger issuing cities — its notgeld series is modest and largely utilitarian in ambition.

The Funck reference places this within a documented local series, though surviving examples in unworn condition are uncommon given iron's susceptibility to oxidation.
