I just bought a coin and can't seem to figure out which one exactly it is. Could somebody help me identify this coin?
My "proposals" are these two, but maybe it is something entirely different.
The Beslik is the other name of the 5 kurus, the only thing that changed between those issues is the rosette under the knot on your coin (it was not present during the previous years) ; it's the reason why we consider them as two different types.
So yep, your coin is a 5 kurus (Beslik) of Mahmud II, minted at Kostantiniyye in AH 1248 (1833).
I did realise that Beslik and 5 Kurus was the same, as it says so in the "value" column on both numista pages. But I hadn't seen the difference in design and also failed to determine the year of reign, so thanks for clarifying!
