5 centimes Daniel-Dupuis Epreuve uniface de revers en bronze, listel fin

The Dupuis centimes series emerged from an open competition launched by the Monnaie de Paris in the mid-1890s to refresh France's minor coinage. Jean-Baptiste Daniel-Dupuis won with a design that broke from the stiff academic classicism dominating French medallic art at the time. This uniface reverse trial — struck with a narrow flan rim rather than the production collar — was produced as part of the official approval process, where individual faces were assessed separately before a combined working die was sanctioned.

The thin listel distinguishes this piece from the standard épreuve format. GEM 14.13 is among the more precisely documented trial varieties in the Frossard-Gadoury reference framework.
