you need to post the whole coin , not just a
bit your coin looks abbasid and
as far as i know gold dinar did not have the mintname written on it.
the
monogram you are referring could be the
sultan`s name
also the key to understanding an
islamic coin is the circular
legend around the calima
in your coin i think (but i could be wrong) i can read (upside down circular
legend at the bottom)
Wa Sanat Sebin
which translates year seventy and is
part of the date
