5 centimes Lindauer Essai en bronze

The Lindauer 5 centimes was designed by Edmond Lindauer and adopted just as France entered the First World War — a timing that effectively killed its circulation life before it began. Wartime metal requisitions and the suspension of normal bronze coinage meant the definitive pieces were barely produced, and the essai series exists largely because the approval process had already advanced before mobilization overtook everything.

GEM 18.4 places this among the documented trial strikes, distinct from the later piedfort variants.
