Thanks Alex. I was wondering if I was going mad lol
There are certainly several aspects that our two coins share and a couple differences as you mentioned.
Overall, the style seems very similar.
As I was using Helvetica's type finder the final two options I come up with is Heraclea 144 and Cyzicus 107.
I think it was the end of the scepter positioning and the rarity rating on the Heraclea that pushed me to assume mine was the more common Cyzicus. Obviously I cant be 100% definitive just using the type finder.
Thanks for reposting your coin and it also gives me the chance to peruse your gallery
