Liard with entwined Cs - Charles IV

Charles IV of Lorraine spent much of his reign in exile, his duchy occupied and administered by France through most of the mid-seventeenth century. He regained control of Lorraine in 1661 — the very year this issue begins — following the Treaty of Vincennes, though French interference in local affairs never fully ceased. Coinage was one of the few concrete expressions of restored ducal authority, which likely explains the deliberate prominence of the royal cipher on this type.

Flon catalogues this as issue 61 within the Charles IV copper series. The 1670 terminus corresponds to Charles's death that year, after which Lorraine passed through a turbulent succession before French annexation was finalized under the 1766 inheritance of Louis XV.
