In Krause there's no coin that seems to match. There are only 3 gold coins with the matching date AH 1323 regnal year 7. The 1/4 zeri mahbub as suggested hasn't two borders like Neilithic says. The zeri mahbub has a total different design. So the only possible coin of those 3 is the 1/2 zeri mahbub (Y# 209b), but there is no picture in Krause. AND, from this coin regnal year 7 is reported, but not confirmed.
I'd say it's fake. The lettering looks quite bad. If you remove the holder you can weight it and I guess it won't fit to the parameters of a gold coin.
I'm not orange and also in other things I'm not a Donald at all. DonChori like Don Felipe or Doña María, por favor.
