Would anyone have knowledge of some coins I will list here? My Grandfather gave these to me in 1968. I remember well the year,for I couldn't wait for 4 more years to pass until at least one of them was 100 yrs. old. The first one to turn 100y/o is a coin,dark in color. It has a 10 in the middle and directly underneath it says Centimes.The other side has a bust of a womans head.Perhaps Royalty? Any Ideas friends? Others I was given are called Pfenigs or something along that line. One coin looks like the star of david and has a hole in the middle. Any info would be very much appreciated.Thnx
