I just found a 1939 French Indochina 10 cents while CRH. I'm not very familiar with this coin, but I tried do some research. What I found was there were 2 version of composition. Nickel and Copper Nickel. Mine doesn't stick to a magnet so I guess Copper Nickel am I right? Also, mine is no dots date. Was it a rare coin? Thanks alot guys!
