5 Francs 1st type Domard Hybride, edge relief

The "hybride" designation here is the critical detail. This variety pairs dies from two distinct 5 francs types that were not intended to be combined — a mule produced at the Paris mint during the transitional period of Louis-Philippe's early coinage. Domard's work on the obverse punch was being phased alongside competing die preparations, and the relief edge lettering distinguishes it from the incuse-edge issues struck concurrently.

Favre #323 documents this as a recognized variety, not an error in the modern sense — the Paris mint's working practices of the 1830s routinely allowed paired use of available dies without the strict type-matching controls introduced later.
