Not a lot, the 5 Franc is Silver 15.00g .835 Silver, .4027 oz ASW. From what I can tell. The issue price was $25 in 84 so who knows. My price book for World Coins is way out of date, me I would go $15 - $25 IF I had any interest in that currency. 14,100 sets made BTW hope that helps
Looking at item: 260739063480... wondering if there is any difference between other 1 oz silver coins like Kooks vs a $5 Maple 1 oz coin???
