Please help in identification of Ancient Macedonia Coin (Maybe Alexander The Great)

Please help in identification. Coin weight is 5.99g diameter 19 mm

Since it is bronze I suspect it is Hellenistic, i.e. post-Alexander. The key should be the inscription on the reverse, but the picture is too dark and I can only read “M” at the start of the first line.
