After an image and article search, it seems your coin is Macedonian, from the period of Roman rule (from 168 BCE).
I could not find any examples that match your specimen, either in the style of the bust (Artemis? Athena?) on the obverse, or the legend on the reverse. Overall, there seem to be a number of anomalous elements to your coin that leave my untrained eye uneasy.
But please, take that with a huge grain of salt as this is definitely an amateur assessment. Once you post the size and weight, the expert takes should start coming in.
