I've got four smallish medieval Arabic coins with a little attribution info which may or may not be correct. Have not been able to find these online, and will greatly appreciate any help.
Coin 1: 2.87 g, 19.5 mm
Identified as Abbasid copper fals ca. 800 AD (remember, all these partial identifications could be wrong!)


Coin 2: 2.02 g, 18 mm
Also identified as Abbasid copper fals ca. 800 AD


Coin 3: 2.07 g, 19 mm
Identified as Reformed Umayyad AE fals AH 79-132


Coin 4: 1.75 g, 16.5 mm
Identified as Mamluke-Ottoman, Al Nasir Nasir Al Din Hasan AH 748-52
