Sorry, but it looks fake.
The details on the obverse (front) looks very crude even at first sight. The seated figure's detail look even more crude.
Search "French Indochina Piastre" and you will see images of genuine ones as well as fake ones.
You can visit this useful website for the specifications of the coin.
