10 cent Indochina 1937 [resuelto]

I just bought this coin. But I wonder that real or fake
it’s weighs 2.69 gram. 19mm diameter, 1mm thickness

Measurements are about right and 1937 seems to be the most common mintage. Is there something specific that has you concerned?

Thank for your reply. Just because some people say that not real. And I’m just newbie so I worry.

Understandable. There are some French Indochina coins that are extremely common fakes of extremely rare coins. Thankfully this one seems to be common enough that it wouldn't be worth faking in the correct material and without the correct material, you're not going to get these measurements.

Good luck collecting!
