Here's an extra pics:

These aren't that great either, but to my unexperienced eyes, they look like just some unknown letters, even in hand, so I'll have to defer to your expert judgement.
Funny enough, all the coins I've been posting lately come from a lot of 200 uncleaned coins I purchased, they've been soaking in olive oil since December and I've just removed them. From them, I will keep about 45 and the rest I will sell on
ebay to recoup my cost. I am quite happy with this lot, seems like a good variety of emperors and some of the coins that have come from the lot (that I have yet to post) are EF (about 8). The coins themselves cost me $225 for the whole lot. Previously I've only really delved into higher value ancients such as greek tetradrachm, republic denarii and byzantine solidus', this is my first time, buying into uncleaned coins.
