French Reunion 1 Franc 1948 Aluminum Apparently there are hungry fishies in the water there, judging by this item in the news today: I also have the 2 Franc coin: French Reunion 2 Francs 1948 Aluminum
Interesting designs. 1948 war the first year when those were issued, and they were made until the mid-70s. Those plants are vanilla and sugar cane by the way ... Christian
