Anciens francs
It is funny to ear "la Marquise" saying : "Nous avons des chambres à 20 000 Francs".
In 1960, we changed our "anciens francs" (old francs) to "nouveaux francs" (new francs) 1 NF = 100 AF.
Like many old persons, la Marquise still speak in "anciens francs" nearly 10 years after and nobody seems to notice.
