Hi guys! This is my first post on this forum, and I am also a total newbie when it comes to coin collecting and selling. We were going through some of our old things and came across this rather old Turkish coin, probably from a great-great grandparent. I'm interested in knowing if the coin experts here can nail down its exact identity and tell me if it's worth anything. I also measured its approximate diameter and weight, if that helps.
Diameter: 22.3 mm
Weight: 7.179 grams
