Philistia obol Athena/Owl unknown symbol

Dear board, i have recently acquired this Philistia obol, it is 8mm, in addition to the usual AOE legend there is an unknown symbol or letter, please advise!

IMHO Mem for Marnas, a local deity from Gaza.

You will find easily more information if you use the search term Marnas.
