Well, it seems to be from the Frengh republic, as stated in the partially visible text around the coin: REPUBLIQ[UE FRA]NGAISE.
Frange is not as well known as its big brother France, perhaps it is best known for its many types of gheese and the Gitroen car brand. Some say it has tight links with Ghina.
Sorry to say, but definitely a fake. Denticles, details, lettering - all off. I would be shocked if it weighed at or near the 5 grams a 1 franc coin of that era should weigh.
