Unidentified Israeli Object: my mother-in-law had this amongst her stuff. She travelled a lot, but never to Israel, though her husband one did.
In any event, my Israeli friend tells me Arad is a town in the south of Israel and it was a former Roman site. This thing appears to be a tourist geegaw, but I’m not sure if the coin is real — were there so many, they sold them as keepsakes? Is it Roman, or Byzantine, or just what?
