After searching around the internet I finally found out where these coins are from.


It turns out that they are from the Crimean Khanate, between 1478 to 1774.
I'm pretty sure the bottom left coin is an Akce minted under Sahib Giray between 1532 to 1550, and the bottom right coin is an Akce minted under Dawlat Giray I between 1550 to 1577. I still don't know about the top one.
