It's rare.
Probably a mint error on the denomination or a pattern / trial version : it wasn't supposed to circulate as the 5 centimes shared the same weight and diameter than this coin.

Only three coins of this type are actually known and two of them are own by the Monnaie de Paris.
People who claimed having this coin have most likely mistaken it with this one : https://en.numista.com/catalogue/pieces939.html
