That is, or was, a French 5 francs - the date is 1947, I think. Problem is that these coins (as the mint made them) should not have a central hole, so that was added by some third party ... In 1947 the coin (type Lavrillier, colloquially named after the engraver) was made in aluminum but also in alu-bronze. See here for example: http://www.lefranc.net/monnaie,5-francs-lavrillier-bronze-aluminium,337.html http://www.lefranc.net/monnaie,5-francs-lavrillier-aluminium,339.html Christian
