Jiaqing Coin? Imitation?

Hi Numista,
I’m no expert when it comes to Chinese coin types/mint marks or Southeast Asian imitations so I was wondering if someone could further help me
identify this coin (22mm, 2.8g).

Thanks!

the reverse side is not readable, therefore, it is impossible to determine the mint.
