10 centimes Epreuve hybride Daniel-Dupuis / Oudiné, double revers

This hybrid trial piece pairs the reverse die of Daniel-Dupuis with that of Eugène-André Oudiné, a combination that would never appear in circulation. The Monnaie de Paris produced such épreuves internally to test die compatibility, evaluate metal flow across competing designs, and preserve a physical record of rejected or competing submissions. Neither side was meant to coexist on a single flan.

Dupuis won the 1897 centimes competition; Oudiné had been the dominant medallist of the preceding generation, responsible for the Third Republic's earlier bronze coinage. The pairing here is almost archival in intent.
