40 Francs - Charles X

Charles X ascended the throne in 1824 after the death of his brother Louis XVIII, and his reign was defined by a reactionary royalism that made him deeply unpopular with the constitutional liberals who had accepted the restored Bourbon monarchy as a compromise. The 40 Francs gold piece was the workhorse denomination of Restoration-era commerce — large enough to matter in significant transactions, common enough to actually circulate among merchants and bankers rather than sit in vaults.

Charles was deposed in the July Revolution of 1830, fleeing to England after only six years on the throne. Issues from his final year, 1830, are the scarcest across all three Fleurus references.
