Help please,
I can't fully identify this coin.
Obv. Laureate head of Apollo right.  Rev. Athena Itonia advancing right, holding shield and preparing to hurl spear. ?EΣΣA / ΛΩN.  However, I understand that the magistrate is shown by the letters on the reverse.  I note A/P.   There appears the be text above the spear but I can’t resolve this.
7.4gr, 18.5-22.1mm & axis 12hr
A full id would be appreciated.
Thanks
