I think the
rev. shows
Isis with
sistrum in raised r. hand and
situla in lowered l. hand, wearing a Lotus blossom on her
head. Usually she should have an
Isis knot on her breast. But on your coin it is hardly to see.
I have added a pic from the famous
Isis statue found in the Villa Adriana. It is your
type. The difference: Here
Isis is wearing a throne on her
head, which is here name in hieroglyphics and was so written too. May be that it is a throne on your coin too?
Best regards
