Ancient Greek coin - helmeted head / cow?

Hello,
Can anyone tell me what this is? At first I thought it was a dupondius with a VRBS ROMA reverse but I didn’t think that was possible and it looks more like a Greek coin...with either Ares or Athena and cow with calf, maybe?

diameter: 18.5mm
thickness: 3mm
weight: 7.72g

This one or similar type...

Macedonian Kingdom: Anonymous (ca. 187-31 BCE) Æ Unit, Pella (SNG ANS 598-609)

Obv: Helmeted head of Athena right
Rev: ΠEΛ-ΛHΣ; Bull grazing right; below, monogram

I think that’s the most likely! The lettering seems to match. Didn’t expect it to be from Macedonia!
