Hello,
It's a half tetarteron of Manuel I minted somewhere in Greece (at Thessalonica or in another mint around).

Please, provide the weight of the coins you post : it makes things easier to determine the denomination and therefor the identification... Diameter varies on ancient coins, the weight is much more relevant.

Byzantine Empire: Manuel I Comnenus (1143-1180) Æ Half Tetarteron, Thessalonica (Sear-1978; DOC 21)

Obv: Facing bust of Christ Emmanuel, raising right hand in benediction, holding volumen in left

​You should invest in a new weight scale in this case : there are cheap ones on sell on Ebay for example.
It's really important to know the weight of your coins when you start collecting ancient / medieval coins or gold and silver ones.
