Hello,
On the obverse (if you turn 90 degrees!) can be seen the name “Mehmed bin Murad Han”. So this is an akçe of Mehmed II (the Conqueror). On the reverse can be seen the mint name, Edirne. The style is type C, so from his second reign. Although the date is off the coin, it would be 875 AH (1471).
Best wishes,
Michael
