I received these four “coins” as part of a large world lot and would appreciate help identifying them. A couple appear to be middle easters and the top left may be old Russian wire money. The uniface (one sided) makes me think a few might be medallions rather than coins. Let me know if anyone has an idea of what is here. Thanks!
All appear to be Ottoman. The coin at upper right is an akche of Bayezid II, 1481-1512, Adrana (Edirne) mint, dated AH 886. https://www.zeno.ru/showphoto.php?photo=222991 The coin at lower left looks like a para (?) of Mahmud II, 1808-1839, Misr (Egypt) mint, dated AH 1223, regnal year 12. The reverse seems to be an incuse of the obverse, possibly a mint error or some type of imitation? https://www.zeno.ru/showphoto.php?photo=85162 The other two are akches. On the coin at lower right, I can make out the mint name "Misr" and a partial date "9xx". I can't read anything useful on the coin at upper left.
