Hello AvDan,
I took another look at the coins. It is hard to tell much specifically about each of them due to the fact that so many of them are crammed into one picture (or two). Try taking pictures of them individually. And as I said, they do appear to be in fairly good condition (that is, you are able to make out some lettering for identification on many of them).
However, the light too, is glaring on them so that makes it hard to see the lettering. Maybe you can do something about that when you take more/better pictures. But there is also another problem. They appear to be mostly copper coins, and of course, they have some pitting. That makes it hard to be certain of some of the letters as well (especially when combined with the glare).
So, what you may do is to dab on a thin coat of oil to the coins that are copper and show pitting. Remove any excess oil. You only want it there to help take away from the 'ashy' areas on the pitted coins. But the oil may also cause some glare. So, you may need to be aware of that when taking pictures of those coins.
I think that I was able to see a Follis of Diocletian (a follis is a denomination of ancient coin). And it also looks like you have an Antoninianus (another denomination of ancient coin) of Claudius 'Gothicus' II. Both are fairly common, but even otherwise common ancient coins may be worth a bit more in higher grade or better condition. Just a few tips that you may be able to use when taking and posting pictures of these coins. I hope that it helps. Kind regards,
