25 Centimes - Villes de Roubaix et de Tourcoing [59]

Roubaix and Tourcoing were under German occupation from October 1914 until the armistice, and the acute shortage of small coin — hoarded or removed from circulation by occupying forces — forced the two municipalities to issue emergency paper together. A joint municipal issue was administratively unusual; the two cities, though neighboring and economically intertwined through the textile industry, maintained separate civic identities. The collaboration was purely practical.

The embossed dry seal served as the primary authentication device — ink-based security printing was difficult to arrange under occupation conditions, and Debode's press was working under significant constraint.
