Roman Coin identification

I got a bunch of small Roman coins from my grandfather. But I could never identify the approximate time or place of origin. He got them from his uncle who was in Tunesia in the 20s from an archaeological site where there were thousands of them. Most are in a pretty bad shape but some could be identifiable.

They are between 10 and 15 mm in diameter, 1 to 3 mm thick and are out of copper.

Coin Side A


Coin Side B



If someone could tell me; even a rough estimate of the time periode would be very helpful.

So I made some pictures of the coins with the most vivible details from above but with out angled lighting the visibility of details is very bad ... I think they are from were now Tunesia is.  

any help in verifying the place and at era would be much appreciated  

1a 1b ~2,5mm thick
1a - Head looking right
1b - Soldier with spear & shield, P to the right   
2a 2b ~1mm thick
2a - Head looking right, letters around (mabe the same as 5b)
2b - looked at from far away: man on the left reachin with his arms in the back galopping horse?
3a 3b ~2mm thick
3a - crowned? head looking right, text right: V S (P/R) F (A) (?)
3b - Soldier?, text around bottom: (?) (M) A R H, right: (?) C C
4a 4b ~2-2,5mm thick
4a - nothing to see
4b - Soldier with spear & shield?, text at bottom (?) (?) (?) (?) (?)
5a 5b <1mm thick
5a - head lookin right text at right (?) (I) (I) (C?)
5b - crowned? man with club? with drawn up legs, text at right: R E P H N H (F?) (?) can't be right
6a 6b ~2mm thick
6a - female? head looking right
6b - left F?, standing figure with staff?, more unclear stuff to the right
7a 7b ~1,5mm thick
7a - little head with laureat? surrounded by unreadable text
7b - nothing to see

The photos are much better and hence will aid in its attribution.  I have some ideas on what the coins are, but let me run through my references first...

Thank you very much ... the places were I look over a year ago had mostly bigger denominations with pictures and everything else with dicriptive texts that helped me not much when I can hardly read a single letter on most the coins

a rough designation is more than sufficient

I think only a rough destination will be possible, but the key to identifying Roman coins is to recognize the portrait and the reverse.  The legend is secondary, but will be helpful to pinpoint the ruler in similar coinage...

Most of these coins are from Constans, but lets start with 2a/2b.  It seems to be a Constans/Fallen Horsemen Coin (see http://wildwinds.com/coins/ric/constans/i.html).  I can't pinpoint to a specific coin, so here is an example.  Note that 2b is upside down...

Roman Empire: Constans (337-350 CE) AE23, Thessalonica (RIC VIII-116)

Obv: DN CONSTA-NS PF AVG; pearl-diademed, draped, cuirassed bust right, holding globe
Rev: FEL TEMP RE-PARATIO; soldier standing left, spearing fallen horseman who is bare-headed, forwards, on hands and knees. Mintmark TSA star

The following coin is NOT mine and hence added for illustrative purposes only:

5a/5b is another fallen horseman and hence follows the previous attribution.  More information on these types of coins can also be found at http://www.forumancientcoins.com/dougsmith/fh.html.

thanks ... and the ones with the soldier are something like this?

In the process of    as it takes time.  Not much to work with, unfortunately...

I am greatful for your help    and I didn't want to hasten you or anything, I just tried to look for something similar to at least write something like "fallen horseman".

Some of them are very difficult to pinpoint to an approximate coin as there isn't much to go by.  The last one, for instance, is just Constans and anything can fit the bill.  Some of the others have some chance, but it takes time as it is a pattern matching game and I don't know all the patterns...
