This small and thick copper coin bears with no doubt the persian Lion & Sun "signature".
I think that it reads " zar(b) Amid" and not "Amul".
Amid (today Diyarbakir in Turkey) has well been under Safavid control for a short time during Ottoman-Safavids wars but no surviving persian coins are known it seems

(the 2 coins listed on Zeno belong, I think, to earlier dynasties).
(on the other hand, no civic coppers from Amul (on Caspian sea) are known...)
The legend is a little smooth and difficult to decipher / no date it seems.
It is to notice that the small script of the die matches to the coin's size (I want to say that isn't a "normal" die struck on a very small flan)
13x 16mm / 5mm thickness / 6,35g
Any Idea or suggestion on it ?
