250 francs - Charlotte Essai - Cuivre

Essai pieces from Luxembourg's 1963 coinage program were struck primarily for submission to the Monnaie de Paris, which was responsible for producing Luxembourg's coinage throughout much of the twentieth century. The 250-franc denomination itself never entered circulation — it existed solely at the pattern and essai stage, making copper strikes like this one trial pieces in the strictest sense rather than collector issues produced after the fact. The Wictor reference, specific to Luxembourg essais, distinguishes several metal variants struck from the same dies.
