So, if the Fall of France was in September of 1940, how come they still exist in such vast quantities? Were they minted before and stored in warehouses? If that is so, why did the Nazis allow them to exist instead of melting them for the war effort or for occupation coins? Why did not Vichy France claim them?
They were issued by the Vichy government, headed by Petain.
France was collaborating with the Nazis, so we had some "agreements", like the right to mint new francs for "the country".
At first the government minted that coins, like the previous ones, so I guess they circulated as well.
However, gold reserves were robbed by the Nazis, they requisitioned the nickel, we had to participate at the war effort and the exchange rate with the Reichmark who was imposed by the Nazis wasn't in favor of the Franc...
So the Vichy government quickly changed the metal of those coins to made aluminium ones before changing the design of them and reducing their weight in a short amount of time.
