Hi all I've posted on here before but will repost using the advice given. I have quite a few more that I'll post over the next couple weeks. This is an ancient roman coin that was part of a bag full I was given years ago. Its relatively light and thin (I don't have a scale sorry) and I've attached a photo with its rough size however it has been bent so not sure if that's much help. Huge thanks and happy to take more photos if necessary.
I am fairly certain Diocletian is the emperor on the obverse. I'm having a hard time making out the reverse though.
It's hard to make out but I believe on the right side there is a figure holding a spear and maybe another figure on the left
This would be a good place to start for you perhaps: http://www.wildwinds.com/coins/ric/diocletian/i.html
could it maybe be this? https://www.coinshome.net/en/coin_d...mpire_(27BC_395)-CzHBwcI0So0AAAEmsdk6TOhF.htm
Same general reverse TYPE but these were struck by various mints and have various control marks. Here are some of mine with similar reverses: Cyzicus mint: Heraclea mint:
