Can someone help me to identify this coin?

Thanks in advance!

Ottoman without doubt.

Please inform the diameter because there are several coins similar to this, and the diameter is the only main difference between them (at least for me). Check here to see what I mean: Numista search using the keywords "ottoman 1223" (the date is AH 1223, regnal year 23).

Thanks for the information. The coin is approx 21,5 mm in diameter.

Its the year 1830 - 1223 / 23 - Mahmud II

You are welcome !
