Year 2 issue meaning it was minted between 285-286AD.

eBid is a ghost town, too many high priced 'buy it now's and not enough low start auctions drive the buyers away. It should be worth about a tenner on ebay.

Bottom right (7) is Byzantine but I'm not sure who it is, someone will know - if its common your probably looking at about £5.

Not sure about the others,

#1 - Not sure what it is.

#2 is a Roman Provincial Judaea - Roman Procurator Antonius Felix. A close up photo needs to be taken and the coin rotated correctly to see the date on the coin.

#3 It is a Judaean coin. It also needs to be positioned right and a closeup photo. Looks like the first Judaean revolt, there is the amphora on the obverse. I can't really tell what's on the reverse.

#4 is also Judaean. It also needs a closeup photo and rotated into position. Looks like Hasmonean. Probably Alexander Jannaeus.

#6 - Some medieval coin. I know nothing about it.

#7 - Byzantine. Difficult to tell which emperor since most of the legends is worn off. A lot of these large folles coins look a like.

I think nr.5
