10 Centimes Silver plated bronze pattern

Pattern coinage under Louis-Philippe was frequently produced at the Paris mint as internal trials, testing both mechanical and aesthetic possibilities without any obligation toward official adoption. This silver-plated bronze piece from 1838 belongs to a well-documented but numerically small family of essais that explored alternative compositions for the decimal centime denominations — the plating itself a deliberate simulation of silver's visual authority at reduced metallurgical cost.

The variant references across Gadoury, Mazard, and KM suggest differing die combinations or planchet preparations that catalogers have not fully reconciled into a single type.
