It doesn’t strike me as fake from the images, as for which coin - no idea!
The last time I had a Roman coin it took me about 2 days of just looking through the Roman coins to find it, I used dimensions to narrow the search but it wasn’t there, I found one similar and put in a date range from that period which gave me a whole lot of searching to do. Mine weighed less than recorded which is why I didn’t find it at first, and it was caked in hundreds of years of dirt which is why I couldn’t make out any script, after 2 more days of restoration it turned into a really nice bronze coin. I don’t really go out of my way to collect ancient coins, just make sure I know what I have if and when I do come across one in a lot purchase.
