Most of my Holy Land uncleaned coins are ordinary Roman coins in fairly rough shape. There are lots of unfamiliar ones, though; typically from the Nabataean Kingdom. I'll post a photo of one with an anchor on one side and a lily on the other. It looks like a "Seleukid" era coin, maybe from the time of Antiochus VII. At least, there are similar ones on the internet that look like this. Presumably 2nd century BC.
