Help with hallmark on Egyptian gold pendant please

[kerizl]

Hello everyone, any help with deciphering the markings on this Nefertiti pendant would be greatly appreciated! My aunt bought it in Egypt in the late 60s or early 70s, and gave it to me. she told me it was gold and I have no reason to doubt her. It is marked on both sides of the bail.

I have googled, and although it does not follow standard Egyptian hallmarks (as explained in an answer elsewhere on this forum), one side of the bail does seem to show 18 in Arabic (for 18K?). But I can't make sense of the rest of it, and don't even know if the presumed 18 (I + upside down V) is actually the right way up.

Any info would be very gratefully received, thanks.
