Ottoman gold coins

Hello, I have a question for you. I have few goldcoins but i don’t know how much they are worth and from what year the coins are. Soo i would really appreciate if someone could tell me.

We would need photos of each coin both obverse and reverse. Weight, diameter and other information would be helpful. Do you have 5 coins coins total? We don't know what we are looking at here exactly.

I have 16 of the litlle ones. They are 13.8mm and they look like that (the both sides)

I also have 2 of the bigger ones 18.8mm. It looks the same on the both sides.

and i have that one 15mm

I am afraid that these are ultimately belly dancer replicas of coins. Nothing adds up. The first one represents itself to be the year 1807/1808 and nothing matches. The second one has both obverse and reverse the same? No, that can't be and be genuine. The third one represents itself to be something like the attached, doesn't add up.
