100 Francs - Louis Philippe Pattern

This 1831 piece is an essai struck in tin rather than gold, produced to demonstrate the proposed 100-franc denomination under Louis-Philippe following his elevation to the throne during the July Revolution of 1830. Pattern coinage of this type was submitted for approval by engravers and mint officials, not intended for circulation. The Gadoury and Mazard references confirm its status as a recognized trial piece rather than a fantasy or later restrike.
