How to Authenticate a Genuine 18th-Century French Commode
For anyone assembling a serious collection of 18th-century French furniture, learning to authenticate a commode is not optional homework, it is the foundation everything else is built on. The difference between a museum-quality piece and a well-made later copy often comes down to details most buyers never learn to look for. Start with the stamp: after 1743, French guild law required master cabinetmakers, the maitres-ebenistes, to stamp their work with their name, typically on the back rail or underside of the carcass, alongside the JME mark of the Jurande des Menuisiers-Ebenistes guild. Names like Riesener, Leleu, and Carlin still command attention today precisely because their stamps can be verified against guild records. A crisp, correctly placed stamp is reassuring, one that looks too fresh, or sits somewhere a genuine maker never signed, is a signal to look closer.
Construction and hardware tell the rest of the story. Genuine 18th-century case pieces were built from solid oak or pine carcasses, hand-cut dovetails, and veneers laid by hand, irregular, slightly uneven, honest. Machine-cut dovetails, uniform veneer thickness, or plywood backing are 19th or 20th century tells, no matter how convincing the surface looks. Run a hand along the underside and the back, that is where restorers rarely bother to disguise their work. The bronze mounts deserve the same scrutiny: mercury-gilt ormolu, hand-chased and fitted individually to each piece, has a warmth and depth electroplated reproductions cannot replicate. Hand-fitted mounts show slight individual variation from piece to piece, while cast reproduction sets are often identical to the millimeter.
Then there is provenance, which matters as much as the physical evidence. A documented chain of ownership, prior auction records, a published catalogue raisonne, a family history that can be traced, does more than support value, it corroborates everything the stamp and construction are telling you. I always tell clients to buy the paper trail as seriously as they buy the piece. A commode without provenance can still be genuine, but one with a strong provenance is a piece you can defend for the next fifty years.
None of this replaces expertise. A trained eye, ideally one that has handled hundreds of pieces across decades, will catch what photographs and checklists cannot. But knowing what to look for changes the conversation you have with a dealer, and it should. A great commode does not need convincing. It simply needs to be understood.
