I'd need some help identifying these coins please, So the bust looks like Octavian, with the reverse shows what I assume is a galley? This coin appears to be of Hadrian, but who is on the reverse? I doubt it's Sabina, afaik I've never seen a coin of her with her hair in a bun!
More likely to be Marcus Aurelius and Faustina II, I think. There are a fair number of such coins, such as RPC IV.3, 4980 and RPC IV.2, 6412.
But the obverse looks much more like Hadrian. I don't see any trace of a beard. I agree that the reverse is not Sabina. Perhaps it's a local city Goddess?
It appears the reverse bust's hair is bound with a wreath of ivy leaves - on that basis, I'd second dltsrq's guess that Dionysos is the reverse type. Possibly something like this - if so, the seeming hair "bun" may actually be the pine cone end of a thyrsos over his shoulder? https://www.acsearch.info/search.html?id=303426
