Thank you Vic and Anthony, the mintname is in the upper left quarter and it is really difficult to decipher because the script is not usual and alas Maythem it isn't Ahmadabbad

it's well a persian mint, not the commonest, but however well known.
I have to say that's because I have seen this similar obverse (same script and ornaments) on a coin of +/- half weight, I am certain of its attribution. (a coin with a camel on reverse).
I think that it is dated "xx52" , 1052AH probably (at 9 o'clock).
What I'm not sure is which bird it is ? a pigeon ?
(I'll give the solution tomorrow, so that you have the night to find

)
