I have managed to somewhat identify some of these, but I would like a little more information. Also if anyone happens to know the current value of anything, or face value, I'd be interested in knowing. I think this one is emperor Constantine but I don't know which one. Anything behind this coin would be greatly appreciated, like where it would be commonly used. I think it was minted in Rome, because of the R, but I might be wrong. I haven't the faintest idea about any history behind this coin. It says it was minted in 1700, and I think it might be from Sicily, but other then that I'm ignorant. I think this coin is in current circulation from Egypt or somewhere in the middle east. I don't know much about it beyond that. Thanks for any information you can provide!
I think its this for the one of constantine, Constantine AE3. 315-316 AD. IMP CONSTANTINVS P F AVG, laureate head right / IOVI CONS-ERVATORI, Jupiter standing left, holding Victory on a globe and sceptre; an eagle with wreath in its beak, left, G to right, dot SIS dot in ex. Siscia (mint) RIC VII 15,G http://www.wildwinds.com/coins/ric/constantine/i.html
I'm not too sure about the Hebrew, but I would very much appreciate being asked before using my photos.
The Sicily coin looks like a copper Grano of Charles II. Here is one from 1699 posted on a British metal-detecting website: http://www.ukdfd.co.uk/ukdfddata/showrecords.php?product=20390&cat=17 These coins got around. The guy found it in England.
