That makes perfect sense! I also have a very old French coin bracelet contains eight 20 real silver centimes from 1809-1887? Most of them have the second emperor's head. Two from 1863. I wonder if convert the coin to jewelery will defect the coin value?( no holes on it) sorry I got so many questions, I'm very new to the coins world as you can tell, it's so fascinating! I admired your knowledge so much!
