Genuine Or Fake? French Indochina ½ Tael

I don't think there are too many experts on these rather exotic coins, but while hoping one shows up and gives an assessment, I can at least give my opinion, based on some experience of French Indochinese coins and what I have seen about the wartime taels (but I don't have one myself).

To me it looks genuine. Weight and measurements are within limits, characters look correct, the fields seem to have the right texture. Typical fakes of this and other wartime taels have smoother features and usually design elements are not quite correct.
