In the decade following the end of the First World War, there was a shortage of small change in circulation. To counter this shortage, everyone started to produce coins for the currency: cities, departments, regions and also factories, stores. For example, these stamp-coins from the novelty stores (later grouped into the Galeries Lafayette group) "Aux Dames de France" in Bordeaux or "A la Riviera" in Nice.



But if it is certain that your token comes from this chic department store in Nice, it is not certain that they are centimes because in France, it always says CTS or C or CMES, CS, etc...
Maybe it is a deposit or dressing room token?
