Identification

I have a coin that I can't identify on our site or on other specialized sites. It is clear that it is a Turkish (Ottoman) coin. It is most likely a copy (a fake from the era, because it was taken out of a jewelry box of my great-great-grandmother, where there were several coins transformed into necklaces - Turkish and Austrian. All made of silver and gold.) The year is identified as 1187 Hijra, and the year of the sultan's reign is III, a little less logical. The coin (i.e. the supposedly fake piece) has a mass of 2.76 grams and a diameter of 32 mm, a thickness of 0.35 mm. Most likely made of brass by mass and color. But I am most interested in which coin it could be a copy of. thank you.
